An Elasto-Plastic Constitutive Model for Unidirectional Fiber Reinforced Metal Matrix Composites

Abstract:

A statistical constitutivemodel, which takes account the effect of strain rate, was presented to describethe stress-strain relationship of unidirectional fiber reinforced metal matrixcomposites (UFRMMC). To verify its reliability, tensile tests on a unidirectionalSiC/Al composite wire, were carried out at different strain rates, and thestress-strain curves were obtained. The testing results show that both thestrength and ductility of the composite wire all increase with increasingstrain rate. Simulated stress-strain curves, derived from the constitutivemodel, fit the tested results well, which indicates that the model is valid andreliable.
