The Relationship

Fracture of coating materials often occurs at or near the interface, while the mechanism and criterion of interface fracture are not clear yet. A molecular dynamics simulation method was introduced to simulate the interface crack initiation, and the relationship between the interface stress and the interface fracture was found. Although a simplified model was applied, the results still showed some intrinsic features that are useful to study the process of interface fracture. At last, an interface fracture criterion was proposed.
