通过迭层复合材料板的基体横向裂纹和界面开裂两个常见损伤问题 ,论述用微观力学方法 ,即把含不连续缺陷的弹性体处理为边值问题求解 ;以及用断裂力学的应变能释放率准则确定损伤萌生和扩展的临界条件。最终都可以得到损伤本构关系
Through the two common damage problems of the transverse crack and interfacial cracking of the laminated composite material plate, the microscopic mechanical method is used to solve the problem of the boundary value including the elastomers with discontinuous defects; and the strain energy release rate Criteria define the critical conditions for damage initiation and propagation. Finally, damage constitutive relations can be obtained
