Bone-Breaking Predictions Put to the Test with FEA
Finite element models of bone have, in recent years, helped us to understand what makes bone strong, and where it’s weakest. To do the latter, though, researchers—and the programs they use—have made their predications with assumptions borrowed from other materials. Naomi Tsafnat, at the University of New South Wales, set out to test those assumptions. She compared the fracture points of a real bone with those predicted by an FE model of the bone made from a Micro-CT scan.
Although it is a product whose job is to lie still, a lot of engineering goes into artificial turf. Designers of the product often call upon engineering software and finite element modeling to get it right. Using Abaqus FEA software from Simulia, a Dassault Systèmes company, a grass-fiber model in can be subjected to virtual bending tests, and its mass, shape, height, etc. modified and retested, until the desired characteristics are achieved.
Finite element analysis is one of several approximation tools for modeling real-world performance for a variety of products and structures. The technique is not foolproof, however, as correctly interpreting outputs requires significant engineering savvy.
