Title:Symmetry and Reciprocity Breaking in Electromechanical Metamaterials and Structural Lattices

Abstract: Recent breakthroughs in condensed matter physics are opening new directions in band engineering and wave manipulation. Specifically, challenging the notions of reciprocity, time-reversal symmetry and sensitivity to defects in wave propagation may disrupt ways in which mechanical and acoustic metamaterials are designed and employed, and may enable totally new functionalities. Non-reciprocity and topologically protected wave propagation will have profound implications on how stimuli and information are transmitted within materials, or how energy can be guided and steered so that its effects may be controlled or mitigated.

The seminar will briefly introduce the state-of-the-art in this emerging field, and will present concepts exploiting electro-mechanical coupling and chiral and non-local interactions in mechanical lattices. Shunted piezo-electric patches are exploited to achieve time-modulated mechanical properties which lead to one-directional wave propagation in one-dimensional mechanical waveguides. A framework to realize helical edge states in two identical lattices with interlayer coupling is also presented. The methodology systematically leads to mechanical lattices that exhibit one-way, edge-bound, defect-immune, non-reciprocal wave motion. The presented concepts find potential application in vibration reduction, noise control or stress wave mitigation systems, and as part of surface acoustic wave devices capable of isolator, gyrator and circulator-like functions on compact acoustic platforms.

Title: Advanced Manufacturing in the Lightweighting of Military Ground Vehicles

Abstract: Weights of military ground vehicles have been continuously rising in response to ever-increasing threats and expanding vehicle protection areas to those threats. This has resulted in reduction of expeditionary capabilities and in increased costs and sustainment challenges. Being expeditionary ensures that the Army retains operational advantages while (1) increasing global, operational, and tactical mobility, (2) improving global responsiveness. The Army’s ability to project forces, conduct forcible and early entry, and transition rapidly to offensive operations is critical to ensuring access and seizing the initiative. The US Army has developed a Lightweight Combat Vehicle Science and Technology (S&T) Campaign (LCVSTC) with specific recommendations in organizational, design, material and manufacturing domains. One of the findings of the cross-organizational team performing the strategic review was that the predominant hurdles in enabling lighter ground vehicles do not necessarily lie purely in materials science research, but rather in the Modeling and Simulation (M&S) and manufacturing technologies required for the same. These and other campaign recommendations that the Army develop clear metrics quantifying an understanding of the operational impact that weight reduction has to the Army will be discussed in more detail. This talk will provide the underlying motivation for light-weighting of military ground vehicles, and the similarities and differences to corresponding efforts for commercial vehicles. The application of advanced manufacturing in the light-weighting of military ground Vehicles will be discussed. Research and innovations in different areas such as Friction Stir Welding and other Multi-material joining technologies, Additive Manufacturing, production processing and development of advanced steel and aluminum alloys, corrosion mitigation, etc., will be described.

Title: Perspectives in Advanced and Nano Manufacturing

Abstract: Advanced manufacturing is the application of innovative technologies to accelerate product development, customize products, increase production efficiency and reduce cost. There is a need for rapid transfer of S&T research into manufacturing processes and products. Products are getting complex, require a high level of design, need to be exciting, reliable and affordable and meet societal needs. To meet these product requirements, new manufacturing approaches are needed. In the last several decades, novel process technologies have emerged—CAD/CAM/CAE, precision systems, IT, robotics, intelligent systems, automation, advanced control systems, new production platforms, mass customization, and green manufacturing. The interest in advanced manufacturing is driven by the need to maintain US manufacturing competitiveness, globally. To achieve this goal requires moving efficiently and rapidly from research to prototype to product. The challenge is to close these gaps, which can be done by developing a close connection between research, design and production. Production innovation is most efficient when tied to a close understanding of manufacturing processes. To transform production, new manufacturing paradigms involving cyber, nano, additive, smart, etc. need to be cultivated. Nanomanufacturing, in particular, has achieved significant advances over the last two decades. It is the fabrication of nano-scale building-blocks (nanomaterials, nanostructures), their assembly into higher-order structures (nanodevices and nanosystems), and the integration of these into larger scale systems. Nanomanufacturing research is the study of processes to manipulate and control matter at the nano-scale, reproducibly. The nano-scale dimension is one where a significant benefit in materials behavior occurs, usually, 1-100 nm. Top-down (e.g., lithography) and bottom-up (e.g., self-assembly) methods and techniques make up a suite of more than 150 nano-scale processes. Integration could be across length scales, geometries, materials and functions, and could provide a means of forming complex, heterogeneous systems exhibiting unusual properties. The goal is to bridge the gap between nanoscience discoveries and nanotechnology products. NSF is advancing research in nanomanufacturing through several programs. These support fundamental research to enable and improve the large-scale or customized manufacture of nano-scale materials, structures, devices and systems, backed by model-based experimental verification and process validation approaches. A key focus of the programs is research leading to new nanomanufacturing methods, tools and platforms. Projects address manufacturability challenges such as scalability, customizability, sustainability, efficiency, controllability, yield and cost, and involve studies of unit processes, in-line and off-line metrology and closed-loop process control. This talk will give research perspectives in advanced and nano manufacturing and discuss future opportunities.

Title: The Role of Composites in Avian Inspired Morphing UAVs

Abstract: The aerodynamics and control that birds using in gliding result in efficiencies in performance not yet realized by fixed wing aircraft. With the advent of smart, multifunctional composites, it is now possible to implement motions inspired by avian gliding in small, unmanned air vehicles (UAV). Initially motivated by the casual observation of flight control motions made by birds, morphing research has proceeded with only limited understanding of how and why birds use their aerodynamic surfaces for flight control. In addition, previous research has not made use of the full spectrum of active materials. A summary of relevant previous results from two fields: avian biology and morphing aircraft, is presented followed by current results on morphing trailing edge research and rudderless yaw control.

It is noted that birds to not have a vertical tail yet have substantial yaw stability and control. By integrating smart materials into the rudderless tail of a small UAV yaw stability and control is investigated in the wind tunnel. The tail consists of Macro Fiber Composites (MFCs) consisting of PZT rods oriented at θ degrees were simulated to induce bending twisting coupling in the control surface. When actuated, the resulting deformation has a novel curvature, which is used to produce a restoring moment over a large range of sideslip angles. This work shows that the complex 3D curvature induced by the MFCs substantially aids in increasing the yaw moment, maintains directional stability and increases stability in diving maneuvers.

Birds also use a shape changing trialing edge in gliding maneuvers. Here we present a combination of shape memory alloys and MFCs to experimentally investigate the aerodynamic advantages of shape changing, spanwise trailing edges for small UAVs. This work investigates the capabilities of the a smart composite trailing edge to adapt to nonlinear aerodynamics which is then applied to stall recovery, by tailoring the trailing edge deflection of the six actuators. In order to predict the actuator configurations for stall recovery, a model which accurately captures the nonlinear behavior of finite wing aerodynamics.

Title: Virtual Material and Structural Testing of Composites: Micro / Meso-Modelling and Associated Multiscale Computational Tools

Abstract: Despite many studies since the beginning of the eighties, the prediction of the mechanical response up to failure of composite structures remains a challenge from a scientific as well as an industrial point of view. This is due mainly to (i) the large number of parameters involved in the design of composites and (ii) the complex state of stress which leads to the initiation and the propagation of damages up to failure? In industry, the damage tolerance prediction is based on semi-empirical criteria. Prior to using such criteria, industries are led to perform very large numbers of experimental tests in order to certify this tolerance.

One of the industrial objectives is to replace some of these numerous these tests by numerical simulations, in other words, to perform Virtual StructuralTesting (VST). The novelty is that now industries are confident that this is possible. In fact, thanks to the increasing power of computers, the calculation of refined delamination has become affordable, which has led to new research projects in this area, which was less active a few years ago.

In the last twenty years, there have been many advances toward a better understanding of damage mechanisms and the mechanics of laminated composites, both on the microscale and on the mesoscale coupled with the development of advanced anisotropic material models. In fact, today, some industrial programs do include more or less refined composite damage models. Industries seek confidence in models and in numerical techniques not only for static loading (calculation and optimization of joints) or quasi-static loading (low-velocity impact), but even more for dynamic loading (composite shock absorbers, impact simulation on composite parts for aeronautics). A similar requirement concerns the delamination tolerance regarding initial delamination defects.

On all these questions, progress has recently been made but is still far from sufficient. Some of the corresponding challenges, which will be addressed during the presentation, are:

  • the confidence in the model: micro-model vs. meso-model
  • the robust calculation of failure (delamination, failure in compression ...)

Unfortunately the use of micro or meso models leads, even for simple specimens, to enormous difficulties such as the huge required number of degrees of freedom Hence the simulation of industrial structures is not affordable with traditional computational approaches. Therefore damage in composite computation appears to be a fantastic playground for all the emerging computational techniques and in particular non-linear multi-scale strategies suitable for large parallel computing.

Title: Interfacing Humans and Machines: Robotic Exoskeletons, Bionic Prostheses, and Mobile Brain Imaging

Abstract: Robotic technologies have greatly advanced in recent years, enabling the creation of new wearable sensors and motorized devices. Robotic exoskeletons for human performance augmentation or neurological rehabilitation are in development and testing at many locations around the globe. Bionic lower limb prostheses are becoming practical solutions for amputees. However, one of the fundamental roadblocks for both robotic exoskeletons and bionic prostheses is the control. Better control approaches are needed to make the devices move in smooth coordination with the human users. One possibility to get better control of wearable robotic devices is to obtain feedforward neural commands from the user. Dan Ferris will present on research aimed at merging humans and machines, outlining the major obstacles remaining to produce truly cooperative human-machine systems.

Title: Neuroprosthetic Engineering With Artistic Expression Via Additive Manufacturing

Abstract: Access to functional bionic devices for pediatric and adolescent patient groups is limited due to significant challenges. High monetary device costs coupled with rapid physical growth by users has yielded a limited accessibility paradigm. Further, traditional devices have historically demonstrated high rejection rates from children who do have access. To change that, our team formed Limbitless Solutions, an engineering innovation company that helps children in need through the design and delivery of 3-D printed bionic limbs and disability technology that are donated to every family. By re-framing the disability challenges with technology and art, we helped the kids discover and freely express their own identities without fear. The non-profit organization is a direct support organization for the University of Central Florida, uses additive manufacturing to advance artistically personalized bionics and solutions for disabilities. Their work focused on combining non-organic forms with colorful design elements to foster user adoption. The use of electromyographic sensing at the distal abbreviated limb allows for reliable bio-sensing used to activated motors for grip control. Signals processing of electromyographic waves allowed for reliability and minimal adaptation time when calibrated.

Further innovation has continued with the first of its kind Xavier hands-free wheel electromyographic wheel chair control system. This system allows for wheel chair users with limited dexterity where otherwise a joystick could not be used for navigation to remain independent by providing direct control with facial muscle gesture control. This advancement has the potential to impact the lives of patient groups that otherwise would remain immobile.

Title: Nonlinear Dynamics for Design Across Different Scales: Challenges and Opportunities Abstract: Nonlinear dynamics is a mature field of research that has been traditionally focused on investigation and prediction of dynamical phenomena ensuing from system nonlinearities and/or interaction force fields. There is an on-going paradigm shift in the design of high-performance structures and devices by which new ways are sought to exploit advantageously different kinds of nonlinearities at different scales rather than enforcing constrains to overcome the onset of nonlinear phenomena. Advanced tools of robust nonlinear modelling, analysis, identification and optimization can be turned into powerful design tools tailored for achieving high levels of vibration control authority and synthesis of engineered systems and materials.

First, the general principles of active resonance cancellation based on perturbation techniques are illustrated in the context of magnetically levitated bodies, cranes, and beams. The active control inputs delivered by the different actuators can be shaped to suppress resonances possessing an activation threshold as is the case for parametric resonances or subharmonic/superharmonic resonances.

Nonlinear passive absorbers based on hysteretic nonlinearities can also be designed to outperform linear viscoelastic absorbers in predefined ranges of operation. This is achieved by using wire ropes made of shape memory alloy (SMA) wires and steel wires for which the interwire friction and the SMA phase transformations are the primary mechanisms of energy dissipation. In this context, perturbation methods and differential evolution algorithms are employed synergestically to drive the optimization process triggered by the approximate nonlinear solutions afforded by asymptotics. Examples are shown dealing with sway control of a five-story building and flutter control of a long-span suspension bridge.

In conclusion, recent advances on high-damping nanomaterials made of a hosting matrix with dispersed carbon nanotubes are discussed. The hysteresis exhibited as frictional sliding between carbon nanotubes and the polymer chains of the hosting matrix can be largely modified and optimized by adjusting the micro-structural constitutive features within the developed computational framework to optimize vibration absorption up to unprecedented levels. Recent experimental and modeling efforts are discussed in the context of new directions in material design for dynamic applications.

Title: Diversity in Global Engineering Education

Abstract: Despite a common goal of preparing engineering graduates for the industry and ensuring that they fit into the society to perform their anticipated roles of proffering solutions, the author through her wide travel experiences observed that there is a wide range of diversity in the engineering curriculum globally. These ranges from typical examples of some institutions in Mexico and France having a compulsory undergraduate component of international exposure as part of the requirements for the award of their degrees to the entrepreneurship skill acquisition knowledge required in some institutions in Brazil. It was interesting to note that a strong component in some Chilean universities was encouraging engineering students to participate actively in sporting exercises as extracurricular activities by providing very attractive state of the art sporting facilities. The proximity of the sporting facilities within the engineering building further enhanced participation. While in South Africa, the engineering curriculum has remained traditional with a little shift in responding to global challenges like energy and advanced manufacturing. With the advent of #feesmustfall and #decolonizationofknowledge, a module has now been recently introduced titled African Insight which is a compulsory module for all students at the University of Johannesburg, South Africa including the undergraduate engineering students. The module is intended to devolutionalise colonisation of knowledge; this stems from a country with past history of apartheid. In a further response to the #decolonizationofknowledge, engineering projects are now being tailored to respond to the needs of local communities. Against this background, this paper is aimed at comparing the diversity observed in the engineering curricula across various countries and across some continents.

Title: Solar Energy and Photovoltaic Technologies: U.S. Department of Energy Perspectives on Mechanical Engineering Research and Development Opportunities

Abstract: The U.S. Department of Energy's Solar Energy Technologies Office launched the SunShot Program in 2011 in order to decrease the cost of solar energy to $0.06/kWh by 2020 so that more Americans can take advantage of the clean, affordable power that solar provides. Now with the original SunShot target being within reach, the Department of Energy has committed to a new goal to decrease the cost of solar energy to $0.03/kWh by 2030 to further increase solar utilization and achieve solar deployment across more markets within the United States. In order to meet these targets, SunShot funds cooperative research and development projects on innovative solar technologies with many partners, including companies, universities, and national laboratories. Some of the challenges to lowering the cost of solar energy include increasing the durability of solar energy system components to withstand decades-long outdoor exposure, understanding sources of power performance degradation of photovoltaic modules and inverters over the devices' operating lifetimes, and decreasing the cost of manufacturing solar system components while maintaining high quality products. This talk will explore some of the opportunities in mechanical engineering research and development that can help achieve the new SunShot goals.

Title: Materials Processing Control Using Electric and Magnetic Fields

Abstract: This lecture will present a variety of mathematical models governing fluid flow and possible solidification processes under the influence of pressure, temperature, electric and magnetic fields. It will also illustrate a few applications of such combined fields when they are optimized in order to achieve certain desired features of the flow-field and the solid accrued during solidification. Finally, it will present a vision of the fully automated optimally controlled additive manufacturing using such fields combined with the optimized time-varying chemistry of the mixture of powders used in additive manufacturing.

Creation of arbitrarily shaped objects with specified functionally graded, spatially varying physical properties requires development of algorithms for optimal control of the manufacturing processes that include thermal, electric and magnetic fields. In case of creating composite materials, the fundamental concept is based on specifying a desired pattern of orientations and concentrations of microfibers in the final composite material product. Then, the task is to determine the proper strengths, locations, and orientations of magnets and/or electrodes that will have to be placed along the boundaries of the curing composite part so that the resulting magnetic and/or electric field lines of force will coincide with the specified (desired) pattern of the coated microfibers' distribution. The basic idea is that the coated fibers will align with the local magnetic lines of force. The pattern of these lines depends on the solidifying resin flow-field and the variation of the applied magnetic field.

Thus, the successful accomplishment of the proposed solidification process involves the development of an appropriate software package for the numerical solution of the partial differential equations governing combined Electro-Magneto-Hydro-Dynamics (EMHD) or Magneto-Hydro-Dynamics (MHD) or Electro-Hydro-Dynamics (EHD) involving liquid flow, electric field, magnetic field, and heat transfer that includes solid-liquid phase change.

In the case of additive manufacturing, this concept requires determination of spatial variation of physical properties that will create desired effects on the boundary of the functionally graded object by optimally time-varying chemical composition of the mixture of alloying powders, intensity and frequency of the melting high energy beam and the motion of the beam or the substrate.

In addition, it involves development of a constrained optimization software package that is capable of automatically determining the correct strengths, locations, and orientations of a finite number of magnets and electrodes that will produce the desired magnetic and electric field force pattern in the melt of the solid object been created

Title: The Evolution of Everything

Abstract: What is evolution and why does it exist in the geophysical, biological, social and technological realms – in short, everywhere? Why is there a time direction – a time arrow – in the changes we know are happening every moment and everywhere?

These are questions of physics, about everything. The physics answer is that nothing lives, flows, moves and morphs unless it is driven by power and has freedom to change. The power is destroyed by the flows, and the flow architectures evolve into configurations that provide progressively greater access for movement.

The universal natural tendency to ‘evolve’ was placed in physics by the constructal law (1996). In this lecture I show why this law is useful to us. We are the evolving "human & machine species." Evolution can be put to use in our lifetime in technology, transportation, urban design, spreading and collecting, miniaturization, communications, science, government and the unstoppable march to freedom, access, wealth and knowledge.

Title: Biological Cell-Matrix Interactions in Fibrous Extracellular Materials

Abstract: Biological cells are complex living systems that can be viewed as micromachines, which derive many of their mechanical functions from the molecular motors within the cell. The force that cells apply to their surrounding extracellular matrix through focal adhesions control processes such as growth, adhesion, development and migration. A new experimental approach to quantify three dimensional full-field displacements and tractions due to cells embedded in a fibrous matrix is presented. Cells and their surrounding matrix are imaged in three dimensions using laser scanning confocal microscopy. Cell-induced matrix displacements are computed using digital volume correlation. The full-field tractions are computed directly from the displacement data. The simultaneous imaging of the cell and the labeled matrix enables the study of cell-matrix interactions and the consequences of matrix remodeling due to cell-induced forces. The three dimensional traction force microscopy technique is used to investigate how cells employ physical forces during cell division, spreading and sensing. In a three-dimensional fibrous matrix, dividing cells apply tensile force to the matrix through thin, persistent extensions that in turn direct the orientation and location of the daughter cells. During spreading, cells extend thin protrusions into the matrix and apply forces using these protrusions. These forces lead to the formation of localized intercellular bands of tensile deformations. A constitutive model for a fibrous material to simulate deformations induced by cells is presented. It is shown that cells in a fibrous matrix induce deformation fields that propagate over a longer range than predicted by linear elasticity. The model captures measured cell induced matrix displacements from experiments and identifies loss of compression stiffness due to microbuckling of fibers as an important mechanism for long-range cell mechanosensing.

Title: Modeling Mesoscale Heterogeneous Plastic Deformation

Abstract: Plastic deformation generally occurs by a series of discrete events, including, for example, glide of dislocations between obstacles, deformation twinning or the atomic rearrangements known as shear transformation zones (STZs). A method for solving plasticity problems with plastic deformation arising from the evolution of a collection of discrete carriers of plasticity will be discussed. Both dislocation plasticity and STZ plasticity will be considered, but a main focus will be on STZ plasticity, in particular for metallic glasses. At each instant, superposition is used to represent the boundary value problem solution in terms of a collection of discrete entities, which are given in terms of analytical solutions for an infinite elastic medium, and an image solution that enforces the prescribed boundary conditions on the finite solid of interest. The image problem corresponds to a standard linear elastic boundary value problem. Constitutive relations are specified for the kinetics of the dislocation motion or for the STZ transformation. Solutions to a variety of boundary value problems will be presented to illustrate the capabilities and potential of the framework. Needs and opportunities for extending the framework will also be mentioned.

Title: New Observations with Multiphase Flows: From a Classical Instability to Membraneless Filtration

Abstract: Fluid mechanics is a discipline with rich phenomena, spanning a wide range of laminar and turbulent flows, instabilities, and applications in industry, nature, and biology and medicine. The subject of "complex fluids" refers to flows where the complexity is introduced by the presence of interfaces, suspended particles (e.g. cells, polymers), multiple phases, and includes soft boundaries, electrokinetic effects, etc. These problems naturally link the subject of fluid mechanics to many science and engineering disciplines. I will provide examples of our work highlighting (i) new features of classical instabilities triggered (and controlled) by changes in geometry, (ii) unexpected dynamics in single-phase and multi-phase flow at a T-junction, and (iii) a new electrokinetic approach for membraneless filtration of aqueous solutions, which suggests a potential technology and use in resource-poor settings. The themes will be illustrated by a variety of results from experiments and simulations, with brief remarks about available quantitative understanding.

Title: Combining Microfabrication and Tissue-Engineering Processes to Advance Nerve Interfaces for the Control of Advanced Prosthetic Limbs

Abstract: Microfabricated electrodes are often implanted into the brain, spinal cord, or nerves in order to record or stimulate neural activity. The goal of such work is typically to advance neuroscientific understanding or to develop new therapies or solutions for nervous-systems diseases or injuries. For example, nerves are a promising target for neural interfaces used to control sophisticated robotic limbs. However, to provide rapid and precise prosthesis control and to elicit high-resolution prosthesis-related sensory percepts, a nerve interface needs many independent motor and sensory channels. Unfortunately, all existing non-invasive and non-regenerative nerve interfaces grossly under-sample the heterogeneous population of efferent and afferent axons. Although tissue engineering, nerve regeneration, and implantable neural-electronic interfaces are individually well-established fields, we believe that the scalability and reliability challenges of nerve interfaces can be overcome by using a technology that combines these fields. We call our novel combinatorial approach tissue-engineered-electronic-nerve-interface (TEENI) technology. In this presentation I will discuss the challenges of neural interfaces, identify the limitations of existing microfabricated approaches, and describe our scalable TEENI technology.

Dr. Judy's research involves the development of novel micro-electro-mechanical systems, such as microscale and nanoscale sensors, actuators, and systems, and their use in impactful engineering, scientific, biological, and medical, applications. A particular focus is in the field of neural-interface technology and systems, with applications in bi-directional prosthetic control, movement disorders, and the autonomic nervous system. Previously, Dr. Judy was a Program Manager in the Microsystems Technology Office (MTO) of the Defense Advanced Research Projects Agency (DARPA), where he created and managed the Reliable Neural-Interface Technology Program (RE-NET) to address the fundamental, and yet at the time largely overlooked, critical reliability problem of chronic neural-recording interfaces. Without successfully developing and translating to the clinic high-performance neural-recording interfaces that function for the life of the patient, many of the widely envisioned clinical applications for brain-maGemstchine interfaces and other neural-electronic technologies will not be realized. Dr. Judy served at DARPA while on leave from his faculty position at the time in the Electrical and Biomedical Engineering Departments at UCLA, where he also served as Director of the NeuroEngineering Program, the Nanoelectronics Research Facility, and the Instructional Microfabrication Laboratory.

Title: Uncertainty Quantification for Reliability Analysis and Decision Making in Engineering Systems

Abstract: This presentation will discuss current research on uncertainty quantification and aggregation for reliability assessment and decision-making in engineering systems. Model-based simulation is attractive for the reliability analysis of systems that are too large and complex for full-scale testing. However, model-based simulation involves many approximations and assumptions, and thus confidence in the simulation result is an important consideration in risk-informed decision-making. Sources of uncertainty are both aleatory and epistemic, arising from natural variability, information uncertainty, and modeling approximations. The presentation will discuss recent advances in the following directions: (1) quantifying and aggregating the effects of multiple data uncertainty and model uncertainty sources on the reliability assessment of multi-physics, multi-scale systems; (2) integrating heterogeneous information from multiple sources (models, tests, experts) in multiple formats using Bayesian networks; and (3) decision support for risk management throughout the life cycle of engineered systems. The techniques will be illustrated with a number of examples from mechanical and aerospace components.
