The Effects of Interfaces on Stress Transfer in Short Fiber Reinforced Metal Matrix Composites

摘要

In this paper, the effects of interface properties on the stress transfer between matrix and fiber in short fiber-reinforced metal matrix composites (SFRMMCs) is studied with the method of the elasto-plastic finite element. The interface properties include Young's modulus, thickness and elasto-plastic performances. In the calculation an interfacial layer with given thickness is introduced into the single fiber model. It is shown that, for a soft interface, the variation in interracial properties influences the stress transfer greatly.
