| 摘 要： | 基于复合材料组分结构的复杂性,通常采用细观力学方法预测复合材料有效模量。本文分析了几种常用的细观力学方法,并采用Eshelby等效夹杂理论与Mori-tanaka方法,编制Matlab程序,分析了含有基体裂纹的纤维增强复合材料的有效弹性模量。选取纤维长径比与损伤含量为影响参数,绘制了有效模量的变化趋势图。

| Abstract: | Based on the complexity of composite's components,the effective elastic modulus are predicted by carrying out microme- chanies method.In this paper,several micromechanics methods are described detailedly,and using Eshelby equivalent inclusion method and Mori-tanaka method,matlab programme is developed to analyse the effective elastic modulus of the composite that con- tains damaged fiber and crack.Particularly,numerical analysis indicate that the aspect ratio of inclusion and the damage proportion are two basilic influence parameter.Finally,this paper gives the trend charts with the change of the effective modulus. |
