Topology Optimization of Coupled Multi-Physics Problems

Abstract

Topology optimization provides a promising approach to systematically design multi-physics problems, such as thermo-mechanical, electro-static, and fluid-structure interaction problems. This class of design problems is often dominated by nonlinear phenomena and is not well suited for intuitive design strategies. In this lecture we will discuss applications of topology optimization methods to coupled multi-physics problems, emphasizing the differences between volumetric and interface coupling in the context of topology optimization. Focusing on density methods, topology optimization of piezo-electric devices and fluid-structure interaction problems will be studied.
