| Abstract: | This paper presents the mathematical model for the optimization of heterogeneous components, and the method using sensitivity analysis and steepest descent method to optimize material properties, the component is then identified. After searching for the materials from heterogeneous material database according to the corresponding optimum material data and combining the heterogeneous components, the material is synthetized. To designer, this method is feasible and effective for the material design of heterogeneous components. |
