Level-set based topology optimization for bi-linear type elasto-plastic problems

抄録

This paper describes level-set based topology optimization for bi-linear type elasto-plastic problems. The geometric complexity can be controlled by the value of the regularization factor τ defined by the phase-field method, and the application of this method to bi-linear elasto-plastic models aims to improve the reliability of structural designs. In this study, a comparison is carried out for the final topologies in elastic and bi-linear elasto-plastic models using 2D and 3D cantilever beam models; we also provide reliable design considerations.
