Notes:
In this paper, the local approach based on the Weibull stress criterion was used toinvestigate the interfacial fracture behavior between LX88A coating and Q345 steel. LX88A coatingwas deposited by high velocity electric arc spraying technology (HVAS). The finite element method(FEM) was used to analyze the stress-strain fields of the coating specimen which consisted of threedifferent specimen geometrics or modes of loading. It was found that the Weibull stress for allspecimen geometries was almost identical under the same fracture probability when the interfacialfracture initiation occurred for different specimen geometries. It showed that the geometrydependence on the interface brittle fracture toughness data can be reduced through application of thelocal approach, and the local approach can be used to describe the interfacial fracture behavior
