In this study, stress distributions on the interface of bonded dissimilar materials with an elastic-plastic interlayer were calculated by using the finite element method and the effect of the elastic-plastic interlayer on the free-edge stress singularity was investigated. It was found that the free-edge stress singularity varied with applied load in the elastic-plastic case. Stress distribution near the intersection of the free-surface and the interface was controlled by the free-edge stress singularity of the bonded dissimilar materials without interlayer as in the case of elastic analyses. Stress distribution near the intersection of the free-surface and the interface normalized considering the free-edge stress singularity can be expressed by a function of the distance from the edge of interface normalized by the thickness of interlayer. The normalized stress distribution can be used to estimate stress distributions for other values of interlayer thickness.
