Cohesive Zone Model (CZM) is a computational technique used in fracture mechanics to simulate the behavior of materials under stress. It is particularly useful for predicting the initiation and propagation of cracks in materials. The CZM approach assumes that the material ahead of the crack tip exhibits cohesive behavior, meaning it can withstand a certain amount of stress before failing. This is in contrast to traditional fracture mechanics models, which often assume that the material is perfectly elastic until the crack propagates.
The CZM is based on the concept of a cohesive zone, a small region of material ahead
The CZM can be implemented in finite element analysis (FEA) to simulate the behavior of materials under
