A functionally graded material (FGM) is a new type of advanced composite material that can be designed for use in thermal barrier coating and in heat shield applications owing to its high service performance that results from the improved mechanical and thermal properties of the material. An FGM is a nonhomogeneous material composed of various constituents and structures that gradually vary over the volume, and their mechanical properties vary smoothly from one surface to the other surface. The purpose of this study is to determine the effectiveness of two-scale modeling for FGM and to analyze its mechanical properties. Models of different volume fractions are developed with aluminum being used as the supporting matrix and silicon carbide being used as the particle inclusions. A geometry with three-point bending test is assumed. Through two-scale modeling, values representing the mechanical properties of the material are obtained at the macroscale level through a full model as well as at the microscale level through a representative volume element. The comparisons of the mechanical properties between macroscale and microscale. Therefore, the two-scale modeling presented herein is found to be useful and reliable for reducing numerical computational time. Based on the results, the stress value deviation becomes smaller as the volume fraction of the inclusion increases. In addition, the results provide evidence for the theory that an FGM has the advantage of smoother stress distributions.
