The materials parameters of functionally graded materials are changed with spatial location. It is difficult to measure the parameters distribution of functionally graded materials point by point according to the experimental conditions. Therefore, the inversion of functionally graded materials and structures is researched by the microelement method in this paper. Namely, the internal parameter’s distributions of functionally graded materials are inversed by the known displacement or natural frequency. This method can greatly simplified the test works of the basic mechanical performance of functionally graded materials.
