This paper deals with a three-dimensional stress analysis of adhesive butt joints subjected to tensile loads in order to contribute to the establishment of the fracture criteria of joints. Dissimilar adherents and an adhesive bond are replaced with finite solid cylinders in the analysis. Stress distributions in adhesive joints are analyzed strictly by the three-dimensional theory of elasticity. The effects of the stiffness of the adherents and the thickness of the adhesive bonds on the normal and shear stress distributions are shown by numerical computations. The stress singularity becomes large at the corners of the interface of which the stiffness of the adherent is large. It is shown that the fracture begins at this interface. The analytical result is also compared with the result obtained by an experiment concerning strain of the adherents. Both results are in fairly good agreement.
