The aim of this paper is to present topology optimization as a method to obtain conceptual designs for crash-worthiness. The topology optimization formulation uses rigorously computed sensitivities. The large displacements and plasticity of the 2D beam elements are modelled with the co-rotational formulation and the plastic zone formulation, respectively. Three examples are presented to show the results of combining topology optimization and crashworthiness optimization. (C) 2003 Elsevier B.V. All rights reserved.
