A structural topological optimization method for multi-displacement constraints and any initial topology configuration

In density-based topological design,one expects that the final result consists of elements either black(solid material) or white(void),without any grey areas.Moreover,one also expects that the optimal topology can be obtained by starting from any initial topology configuration.An improved structural topological optimization method for multidisplacement constraints is proposed in this paper.In the proposed method,the whole optimization process is divided into two optimization adjustment phases and a phase tr...
