Optimal Design for Crashworthiness Using a Plastic Strain Criterion

摘要

The purpose of this paper is to present a new methodology to design the topology of structures for energy absorption such as vehicle structures under crash events. The approach is heuristic in essence, and numerical experiments have shown its uses in real problems. The approach has its foundation on two mathematical tools, an interpolation scheme for the material properties, and a re-design rule (similar to optimal-ity criteria) for the optimization part.
