| 摘 要： | 探讨了实现复合材料细观结构与构件宏观动力特性直接关联的细观元法。细观元法先进行宏观单元剖分，然后分析细观结构，将微结构力学量转化为宏观结点量计算。该方法不增加自由度，但使得微结构层次上任意铺设方式和任意微小变化均能在宏观动力特性上得到反映。

| Abstract: | The microelement method, which establishes the immediate relation between the microstructure of material and dynamic character of structural member in composite material, is discussed. The method, firstly, divides the composite structural member into a set of macroelements, then analyzes the microstructure, and translates the variables of the microstructure into variables of nodes for calculation. In this method, any arbitrary pattern of microstructure and any tiny change will be reflected in macrocharacter without increasing the degrees of freedom. |
