Abstract:  As a new kind of material, composite has the advantage of designable, the designable parameters include the type of the fiber and matrix, the percent of the volume, the direction of the laminate, etc. In this paper, author used the method of microelement which can relate the analysis between the microstructure of material and the macroscopic response of structure member without increasing the number of freedom. Using the method of microelement with the skill of back analysis,we can realize the inverse design and distinguish the microstructue of the composite material.
Keywords: composite, microelement, back analysis.
