Abstract

In this paper the idea of design exploration in the context of structural design sensitivity analysis considering elastoplastic material behaviour is outlined. Sensitivity information involves the influence of history dependent material behaviour and is obtained analytically by means of a variational approach. Applying singular value decomposition (SVD) to response sensitivities provides deep insight into sensitivity information and can be used to identify design changes with major influence on structural response. With this additional information, it is possible to refine an optimisation problem and reduce its complexity. (© 2017 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
