Density-Based Topology Optimization for Maximally Stiff Structure Problem Using Two-Phase Materials

Abstract

Herein, we present numerical results obtained after performing density-based topology optimization for a maximally stiff structure problem using two-phase materials. A maximally stiff structure was modeled to minimize the strain energy of the structure. The Young’s modulus expressed based on a two-phase material, such as a functionally graded material at the junction point, was used in the density-based topology optimization. The two-phase material was completely separated in the optimized structure, and the strain energies before and after the separation were compared.
