Abstract
With today’s increasing and global competition, probabilistic design methods with consideration of uncertainty have been gaining much attention. The consideration of uncertainty enables engineers to make reliable decisions, to lessen quality loss, to manage risk, and to avoid over-conservative designs. However, design under uncertainty poses a challenging and complex optimization problem. Efficient computational techniques are therefore needed. In this talk, recent research developments on quantifying and propagating various types of uncertainties in design, e.g., random field uncertainty, model uncertainty, and material uncertainty will be presented. The use of these techniques in new and emerging fields of multiscale design under uncertainty and topology optimization under uncertainty will be demonstrated.
