摘要
基于能量等效原理，采用三维有限元方法，考虑短纤维位向的随机分布对复合材料弹性模量的影响，利用有限元能量法对δ－Ａｌ２Ｏ３（Ｓａｆｉｌ）／Ａｌ合金复合材料的弹性模量进行了预测。预测结果与实验结果和目前常用的几种预测方法进行了比较，表明该方法是合理、准确的。
Based on the energy equivalence principle, the elastic modulus of Al2O3f/Al composite was predicted by means of the Finite Element Method. In the predicting, the random orientation distribution of short fiber was considered. The results were compared with the experimental values and those of previous predicting methods. In the end, it can be concluded that the method developed in this paper is reasonable and precise.
