| 摘 要： | 等效夹杂物方法是细观力学中的一种重要方法，文中编制的数值计算程序能在考虑多个夹杂物相互响应的情况下计算材料应力、应变场，并实现了计算结果的三维显示．计算结果与文献中的计算结果非常吻合．本文编制的数值计算程序不仅可以用于研究复合材料的损伤演化及失效，而且利用特殊构型的椭球空洞来模拟裂纹，可以计算裂纹群的应力、应变场。

| Abstract: | The equivalent inclusion method is one of the most important methods in the micro mechanics. The computer program dealing with the interaction among multi inclusions has been written and used to calculate the stress field as well as strain field of the material. The calculation results can be illustrated in three-dimensional figures. They coincide with the exact results and numerical computation results in the literatures very well. The numerical computation program can not only be used to study the damage evolution and failure of composite material, but also can be used to calculate the stress field and strain field of collective cracks by using the special ellipsoidal cavity to simulate the crack. |
