摘要
有些复合材料经常发生分层破坏,复合材料纤维的“分层”通常保持在同一平面内的延伸和扩展,类似于断裂力学中裂纹的扩展。将复合材料的混合裂纹看成为Ⅰ型裂纹和Ⅱ型裂纹的叠加,根据断裂力学中能量释放率的观点建立了混合裂纹的断裂准则,并用以分析复合材料混合裂纹的分层破坏现象。
Laminating crack often happens in composite materials. Mixed mode fracture is divided into mode I fracture and mode Ⅱ fracture. A failure criterion has been developed for mixed mode fracture based on the theories of energy release rates and has been used to analyze laminated failure of mixed mode cracks in composite materials.
