Abstract: Based on the quasi-parametric quadratic programming method and discontinuous linear elastic constitutive law model,this paper constitutes the micro-mechanics model of failure process at the fiber-matrix interface and does numerical analysis by finite element.The calculated results show an agreement with that of experiment. -
