Abstract
In this paper, the local approach was used to analyze the geometry dependence of coating
specimens for interface brittle fracture initiation, and a definition of the fracture process zone was
proposed in the paper. The results showed that the interface fracture behavior of two types of
specimens with notch had been predicted from the test results of pre-crack specimens based on the
local approach for interface brittle fracture, and the predicted distribution of the critical load for the
notched specimens gave a good agreement with the test results. It indicated that the local approach not
only can be used to describe the interface fracture behavior, but also can be used in the integrity
evaluation for interface between different materials.
