Optimal design for multi-objective density-based topology optimization using a modified optimality criteria method

Abstract

This paper describes density-based topology optimization for multi-objective problem using a modified optimality criteria (OC) method. Multi-objective problems include strain energy minimization and von Mises stress minimization. The update equation for topology optimization is a map-based modified OC method, which is a modification of the modified OC method. The linear weighted sum method was employed for multi-objective optimization, and the effects of the weights of the linear weighted sum method on the optimal design results was presented.
