基于刚度退化的复合材料结构损伤研究进展

Research Advances in Damage of Composite Structures on Stiffness Degradation

针对复合材料结构的渐进损伤问题,较为详细地评述了近年来的研究进展。首先对强度失效准则的研究进行了分析说明;然后针对结构损伤模型所包含的损伤本构关系、损伤演变方程等方面的研究进展作了详细的论述,此后分别讨论了不同类型载荷作用下的结构损伤研究进展;最后,提出了今后应深入研究的问题。

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 characteris-tics.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 equa-tion.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.
