The stress distributions of single-lap adhesive joints of dissimilar adherends subjected to external bending moments are analyzed as a three-body contact problem using the two-dimensional theory of elasticity. In the analysis, dissimilar adherends and an adhesive are replaced by finite strips, respectively. In the numerical calculations, the effects of the ratio of Young's modulus, thickness and length of dissimilar adherends on the interface stress distributions are examined. As a result it is found that the stress singularity occurred near the edge of the interface and it increases at the edge of the interface of the adherend with greater Young's modulus. It is also seen that the singular stress decreases at the edge of the interface of the adherend with larger thickness. In addition, experiments are carried out and fairly good agreement is found between the analytical and the experimental results.
