摘　　要：针对随机分布颗粒增强金属基复合材料数值模拟问题进行研究,假设颗粒为椭球形,编制模拟多颗粒随机分布复合材料的程序,可模拟出颗粒大小、形状、方位随机的多颗粒增强复合材料,并对拉伸应力场、损伤萌生情况进行分析。Numerical simulation of randomly distributed particle reinforced composite was studied, the program for simulating randomly distributed particle reinforced composite was finished, in which the particles were supposed to be ellipsoids with different shape and orientation. And then tensile stress fields of the composite were simulated and damage nucleation was analyzed.
