“…Shojaei et al investigated the microscale damage mechanisms in CMCs in detail and a continuum damage mechanic (CDM) model is developed within a physically consistent framework to study two common failure modes in CMCs, ie, matrix/interphase fracture and fiber sliding. Min et al developed a micromechanic analysis modeling method to analyze the damage process and fatigue failure of CMCs. The concept of the repeating unit of fiber‐reinforced composite material is used to represent the whole composite structure.…”

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.

“…The method based on microscopic damage mechanism is to establish the mechanical model of fatigue damage based on the meso-fatigue failure mode [ 12 ]. Min et al [ 13 , 14 ] established a multi-scale fatigue calculation model based on micro mechanics for plain woven C/SiC CMCs, and verified the effectiveness of the proposed method by comparing it with fatigue test data of plain-woven C/SiC CMCs. Based on the fatigue hysteresis behavior of CMCs, Li et al [ 15 , 16 , 17 , 18 ] established a fatigue life prediction model which considering the decline of interfacial shear stress and fiber strength during the fatigue cycle.…”

A multi-scale fatigue analysis method for braided ceramic matrix composites (CMCs) based on sub-models is developed in this paper. The finite element shape function is used as the interpolation function for transferring the displacement information between the macro-scale and meso-scale models. The fatigue failure criterion based on the shear lag theory is used to implement the coupling calculation of the meso-scale and micro-scale. Combining the meso-scale cell model and the fatigue failure criterion based on the shear lag theory, the fatigue life of 2D SiC/SiC is analyzed. The analysis results are in good agreement with the experimental results, which proves the accuracy of the meso-scale cell model and the fatigue life calculation method. A multi-scale sub-model fatigue analysis method is used to study the fatigue damage of 2D SiC/SiC stiffened plates under random tension–tension loads. The influence of the sub-models at different positions in the macro-model element on the analysis results was analyzed. The results shows that the fatigue analysis method proposed in this paper takes into account the damage condition of the meso-structured of composite material, and at the same time has high calculation efficiency, and has low requirements for modeling of the macro finite element model, which can be better applied to the fatigue analysis of CMCs structure.

“…The microstructural analysis indicated that the residual tensile strength after cyclic loading was affected by the formation and propagation of cracks and interfacial degradation. Min et al 23 developed a micromechanics analysis for damage progression and fatigue failure of fabricreinforced CMCs. The three-phase micromechanics, the shear-lag, and the continuum facture mechanics models were integrated with a statistical model in the repeated unit cell to predict the progressive damages and fatigue life of composite structures.…”

In this paper, a micromechanical fatigue life prediction method for fiber-reinforced ceramic-matrix composites subjected to stochastic overloading at room temperature is developed. Fatigue damage mechanisms in the matrix, interfaces, and fibers are characterized using different damage models. Relationships between the fatigue life and related degradation rate, stochastic overloading stress, and breakage of intact fibers are established. Experimental fatigue life of different C/SiC composites subjected to different stochastic overloading is predicted. For the same stochastic overloading condition, the degradation rate of fatigue life is the highest for cross-ply C/SiC composite, and the lowest for 2.5D C/SiC composite.
