Abstract:
Topology optimization for crashworthiness is still a challenging task due to dynamic effects and high nonlinearities. In this paper, a new approach is presented based on hybrid cellular automata, which enables optimization using nonlinear and dynamic crash modeling and simulations. A special ground structure approach is used where the cells for the cellular automata are structural entities consisting of a larger set of finite elements and not a single element (voxel) like in approaches available...     »
