Robust topology optimization

TUHH/Benedikt Kriegesmann

Additive processes allow for manufacturing complex structures and therefore provides large design freedom. Topology optimization methods exploit this freedom by providing structures, which contain material only where it is required for load bearing. By tailoring structures to a certain load scenario, classical optimization methods often yield designs, which are quite sensitive to scattering properties such as material parameters or load direction. Robust design optimization techniques provide design solutions, which are lightweight and at the same time robust with respect to uncertainties. The obtained designs often differ significantly from the ones obtained by classical optimization approaches.
