Abstract

A method for topological optimization of structures with discrete variables subjected to dynamic stress and displacement constraints is presented. By using the quasi-static method, the structure optimization problem under dynamic stress and displacement constraints is converted into one subjected to static stress and displacement constraints. The comprehensive algorithm for topological optimization of structures with discrete variables is used to find the optimum solution.
