【摘要】 提出了一种新的复合材料结构中层间脱层裂纹扩展模型，该模型能够揭示裂纹扩展对裂纹左右尖端能量释放率的相对大小及界面材料性能的依赖性，能够比较真实地揭示复合材料结构层间脱层裂纹扩展复杂性的特点．更多还原

【Abstract】 In this paper, a nonsymmetric growth model of interfacial crack is presented. The model can reveal the relation between crack growth and the relative energy release rates at the left and right crack tips and the interfacial material property and better characterize the complexity of the interfacial crack growth.更多还原
