中文摘要：

利用三维有限元方法,通过建立颗粒随机分布胞体数值分析模型,对颗粒复合材料做模拟计算。在单向拉伸荷载作用下,讨论模型中von Mises应力的分布规律以及弹性模量的数值模拟。与实验结果相比较,发现颗粒随机分布胞体模型弹性模量与实际情况符合较好,颗粒内高应力区域与金相显微镜下的颗粒微裂纹吻合较好。

英文摘要：

Using three-dimensional finite element method method , make an analog computation by building the pellet random distribution compatriot body numerical value analysis model, to the particulate composite. Under the effect stretching load unidirectionally, discuss that von Mises strain distribution law and elasticity modulus numerical value imitate in the model. With experiment bear fruit compare, discover the pellet random distribution compatriot body model elasticity modulus according with reality fairly good, pellet inner high stress area is identical with tiny crack of lower metallographic microscope pellet fairly good.
