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.
