Cohesive Zone ModelA mathematical framework used to describe the process of material failure and fracture mechanics by introducing a zone of finite thickness between two bodies where traction and separation are related by a constitutive law. / 一种用于描述材料失效和断裂力学过程的数学框架，通过在两个物体之间引入有限厚度的区域，其中牵引力和分离由本构定律相关联。
