摘要
复合材料作为一种具有复杂结构的新型材料，其主要优点和特点在于其内部结构可设计性。本文利用细观元方法将宏单元剖分和细观结构分析结合起来，不增加自由度数，却能使微结构的变化在宏观力学响应上得到直接反映。在细观元方法的基础上引入反分析技术，就能实现具有复杂结构材料件在细观层次上单参数反演与识别。
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.
