Abstract Scope |
This study aims to identify optimal material distributions for functionally graded materials (FGMs) using multi-material topology optimization. FGMs can support the development of multifunctional material systems that serve various purposes simultaneously. When designing FGMs, stress at material interfaces is a crucial parameter due to mismatches in stiffness. Topology optimization has been used to determine optimal material distributions under an objective function, constraints, and boundary conditions by controlling elemental density. It has been applied to various applications, including multi-material optimization and stress constraints. In this study, multi-material topology optimization is applied to identify optimal FGM distributions. Additionally, von Mises stress is constrained to ensure the specimen's mechanical performance, and a cost function is integrated to minimize manufacturing costs while meeting mechanical requirements. |
