Abstract:

A new primitive cell method is used to investigate the effect of the interfacial properties on the dynamic behavior of ceramicmetal composite material in this paper. This method is the combination of a primitive cell method with random multi-particles based on voronoi diagram and cohesive zone model which is used to describe interfacial mechanical behaviors. By this method, two kinds of interfaces are chosen: one is perfect interface; the other is weaked interface where the interaction between particles and matrix is described by cohesive zone element. We propose this method to predict the dynamic behavior of particle reinforced metal matrix composites. Additionally, we believe the introduction of cohesive zone element gives good pridiction.
