| Abstract: | More attention has been paid to the behavior of thermomechanical fatigue (TMF) of fiber-reinforced metal matrix composites. In this review, main results of the theoretical work conducted recently in this field are discussed. For the thermomechanical cycle behavior, the models of the axial nature based on micromechanical methods and the models of the transversal nature based on fracture and damage mechanics are included. For evaluating thermomechanical fatigue life, two models are deduced from the transerval nature of materials. The influence of the metal matrix's microstructure on the fatigue life is also discussed. |
