| Abstract: | In this paper,a micromechanically analytical model based upon progressive damage mechanisms under cyclical thermomechanical loading,by considering statistical particularity of fiber strength and cyclic response of matrix properties,is developed to investigate fatigue failure of continuous fiber-reinforced metal matrix composites,which is dominated by multiple damage events described by fiber fracture,local cyclic plasticity of matrix and interface,as well as interfacial debonding.A simulation scheme coupled... |
