Abstract

Topology optimization for elasto-plastic materials has so far been mostly limited to the SIMP method and 2-dimensional cases. In the proposed research, the topology optimization is performed for a 3-dimensional elastoplastic material based on the level-set method, and the explicit derivative with respect to the level-set function is adopted in sensitivity analysis. A comparison of the optimized structure between the 3-dimensional elastic case and the 3-dimensional elastoplastic case has been made.
