Mechanical structures undergoing crashworthiness loads can behave very sensitive with respect to uncertainty of loading, geometry and material parameters. In this work, techniques are presented and investigated for design optimization of lightweight space-frame structures considering structural mechanics, including crashworthiness and uncertainty using fuzzy methods. Complementary to the developed optimization approaches, shadow uncertainties and shadow uncertainty prices—based on the idea of Lagrangian multipliers as shadow prices—are derived and applied to post-process results of both uncertainty analyses and optimizations under uncertainty.
