Abstract
Although a lot of interface crack problems were previously treated, few solutions are available under arbitrary material combinations. This paper deals with an edge interface crack in a bonded finite plate and semi-infinite plate. Then, the effects of material combination on the stress intensity factors are discussed. A useful method to calculate the stress intensety factor of interface crack is presented wirh focusing on the stresses at the crack tip calculated by the finite element method. The stress intensity factors are indicated in charts under arbitrary material combinations. For the edge interface crack, it is found that the dimensionless stress intensity factors are not always finite depending on Dunders' parameters α, β.
