| 摘 要： | 粘接界面本构模型的主要特点是不像经典断裂力学根据材料弹性或塑性分析得到宏观的断裂标准来判断是否开裂和扩展。在界面本构模型中,材料的强度和韧度、裂纹的形成和扩展都由界面的本构关系所决定。介绍了目前主要的5个界面模型,给出这些模型的特点和界面开裂时的拉力与位移关系。

| Abstract: | An important characteristic of the interfacial constitutive model for the fracture initiation and propagation is different with macroscopic fracture criteria, which based on elastic or elastic-plastic analyses, In interfacial constitutive model, material strength, toughness, crack nucleation and propagation are all characterized by the local traction-separation relationship and the cohesive surface methodology. The five current main interfacial constitutive models were introduced. These interfacial model characters and the interface traction-separation relation were presented. |
