The Effect of Imperfect Interface on the Dynamic Behavior of Ceramic Particles Reinforced Metal Matrix Composites
A new voronoi representative volume element (RVE) model with Cohesive Zone Models is advanced to investigate the effect of the interfacial properties on the dynamic behavior of ceramic-metal composites in this paper. This method is the combination of RVE with random multi-particles based on voronoi diagram and cohesive zone models which is used to describe interfacial mechanical behavior. Two kinds of interface are considered in this work, one is perfact interface; the other is weak interface which is imperfect(including the strong and weak interface). The mechanical behaviors imperfect interface are described by classical Cohesive Zone Models. By this method, the effect of interface on the dynamic behavior of particle reinforced metal matrix composites had been investigated. The numerical results show that the interface properties have huge impact on dynamic mechanical behavior of composites, strong interfaces will delay the failure of marix; however, the composites will fail rapidly after the interfaces failed while the interfaces are weak.
