Abstract: The progress on the dynamic strength design methods of ceramic matrix composite structures is reviewed. The application status of ceramic matrix composites is introduced, and the key factors in the strength design of structures are analysed, which include multi-scale modeling method, constitutive model, strength model and dynamic analysis. The single-scale and multi-scale methods are compared and the advantages of them are analysed. The frequently used constitutive models of ceramic matrix composites are introduced and it is pointed out that the dynamic analysis needs more appropriate models. The strength models of ceramic matrix composites are introduced, and it is pointed out that the main difficulty is the strength prediction of woven ceramic matrix composites under complex stresses. Then, the dynamic analysis methods of ceramic matrix composite structures, including modal analysis and transient simulation, are elaborated and compared. Finally, the development directions of the dynamic strength analysis are summarized.

Key words: ceramic matrix composites, multi-scale, constitutive model, dynamic, strength
