“…To obtain the precise parameters of the fatigue model, only the material level testing can simulate the complex stress state of the actual structure to fully characterize the fatigue behavior of materials. In fact, the fatigue damage mechanisms observed under fatigue loading including matrix crazing, matrix cracking, fiber/matrix interfacial debonding, delaminations, fiber buckling, fiber breaking/pull out, and finally global fracture, as shown in Figure . More essentially, the fatigue damage process in CMCs is accompanied by progressive damage propagation and stress redistribution behavior.…”

Prediction of fatigue damage and fatigue life in fiber‐reinforced ceramic‐matrix composites under thermomechanical loading is of critical importance in the reliability and safety design of advanced aerospace structures. This article presents a short review of the state of the art for the primary fatigue models in the fatigue life prediction of ceramic‐matrix composites. Two kinds of fatigue models have been introduced: (a) phenomenological models, including fatigue life models, residual strength model, and residual stiffness model, and (b) progressive damage models correlated with macroscopic residual mechanical properties and mesoscopic damage mechanisms. Based on the literature review, the writer recommends that the most effective method for ceramic‐matrix composites fatigue modeling is progressive damage models. Finally, the writer proposes to establish a progressive fatigue damage model associated with the service environment.
