摘要
本文将细观力学的Eshelby和Mori-Tanaka理论与刚度体平均化方法相结合,对含圆币型基体微裂纹的三维编织复合材料弹性常数进行了理论预报,分析了纤维体积含量、微裂纹密度、编织特征参数变化的影响,与文献[3]的实验结果进行了比较。
The elastic constants of three-dimensional braided composites containing matrix microcracks were predicted by Eshelby and Mori-Tanaka theories combined with Stiffness Averaging Method. and their variation with fiber volume fraction. microcrack density and braided parameters was analyzed. The theoretical predictions match the experimental results on reference [3]fairly well.
