this article is concerned with the problem of the importance of rheological phenomena in the yielding and fracture of isotropic material with memory.
本文论述了在各向同性记忆材料屈服与断裂中流变现象的重要性问题。
combining perimeter constraints and the solid isotropic material with penalization (simp) law, the optimal distributions of multiphase materials are obtained by elimination of checkerboards.
