【Abstract】 The damage of composite structures is one of the important reasons for structure failure,but the complexity of composite has brought great difficulty to the research work of structure damage and strength characteristics.The research progress in damage of composite structures in recent years is discussed,especially the establishment of damage model,including macroscopic strength failure criterion,constitutive relation and damage evolution equation.On this basis,the research progress and existing problems of structural damage under different types of loads are discussed respectively.The critical issues in the further research on the composite damage are also discussed.更多还原
