Now in Uncertainty
Demystifying Uncertainty Quantification
As scientists and engineers probe ever deeper into the fundamental mysteries of physics, uncertainty in its many forms looms as a major challenge sound simulations and analyses. Uncertainty quantification and its computer-science cousin verification and validation, emerging sciences in themselves, offer sound methods and solutions.
The field of uncertainty analysis helps engineers answer the seemingly unanswerable: How much do we know about what we don't know? Using high level statistics and probability, the discipline can tell us just how likely it is that any given measurement is accurate. It can also tell us just how often to calibrate to guarantee accuracy. Today's computers allow businesses to avoid recall while also saving money.
Traditional methods of analyzing uncertainty are becoming too expensive and computer intensive to perform in some complex modeling applications, even with high speed computing power available today. To reduce computing time, methods not traditionally applied to uncertainty analysis were compared on reduced order models to solve an aircraft flutter problem.
The division strives to foster the intelligent use of mechanics by engineers and to develop this science to serve the needs of the engineering community. One sub-committee Uncertainty, Probabilistics and Reliability Technical Committee focuses in this topic area.
