Title:
Efficient Robust Shape Optimization for Crashworthiness 
Abstract:
The work presented here focuses on the reduction of computational effort associated with Robust Design Optimization (RDO) for crashworthiness of large industrial models. For the robust design study, the computational effort is determined by the following two aspects: (i) time for the computation of a single crash event and (ii) the number of evaluations required for the robustness of each design. For the first aspect, the possibility of using physical surrogate models (sub-structures or linear m...    »
