Topology optimization of multi-objective crashworthiness structure based on Improved Bi-directional Evolutionary Structural Optimization

In view of the checkerboard and gray cell optimization problems easily occur in the structural topology optimization under the traditional impact load, In this paper, based on the domain idea of cellular automata algorithm and 0–1 idea of bidirectional asymptotic method, an improved bidirectional as...
