In practical application of FGM(Functionally Gradient Material) into Machinery, the optimum gradient must be determined for its best function and the using condition. Generally, strain and strain energy are used as criterions to determine the optimum gradient of FGM, but the general gradient determinants concerning the temperature difference between matrix and reinforcement and the thickness of FGM and ratio of other material properties are rare. In this study, the temperature gradient and the volume fraction were set to solve the general determination of gradient of FGM with factors such as the temperature difference between matrix and reinforcement, the thickness of FGM and ratio of other material properties.
