Improving multi-material structures using topological optimization and the modified SIMP method

Abstract

This paper proposes to use a modified SIMP method to solve the problem of topological optimization of structures containing components of more than two different materials, which must be distributed in such a way as to obtain the best structural characteristics using one continuous design variable. The paper demonstrates the effectiveness of the proposed method by the example of solving the problem of topological optimization of a structure made of multimaterial. With the help of such a solution, it is possible to obtain reliable structures with improved mechanical characteristics, which can be used to solve real problems of design and manufacture of complex structures.
