In this paper, we propose a topology optimization method of a structural members for crash-safety by using density approach. This method is based on the generalized layout optimization method and design variable is a virtual isotropic material whose properties are functions of the element density. Because of the finite element configuration, the optimal configuration tend to have checkerboard patterns and the gray scale density in this approach. For this reason, we applied the gravity control function for design of structural members for crash-worthiness as a filtering method. Moreover we also applied the parallel computing to reduce the calculation time. Several numerical examples are shown to verify the present method.
