In the present paper, the stresses of butt adhesive joints are analyzed by a two-dimensional theory of elasticity in order to establish the fracture criteria when dissimilar adherends are bonded by an adhesive. Dissimilar adherends and an adhesive are replaced with finite strips, respectively, and the analyses are done as a three body contact problem. In numerical computations, the effects of the ratio of Young's modulus of dissimilar adherends, the ratio of Young's modulus of adherends to that of an adhesive and the thickness of the adhesives are shown on the distributions at the interfaces of the joints. As a result, it is seen that the principal stress becomes maximum at the interface between the adhesive and the adherend having high Young's modulus. For verification, experiments are performed. Analytical results are in fairly good agreement with experimental ones.
