In the present paper, replacing similar adherends and an adhesive by finite strips, stress distributions in adhesive joints are analyzed strictly using the two-dimensional theory of elasticity in the case where adhesive butt joints are subjected to tensile loads. The effects of stiffness and thickness of adhesive on the stress distributions are shown by numerical computations. For verification, an experiment is performed, and the analytical result is in fairly good agreement with the experimental one. Furthermore, the analytical result and the result obtained by F. E. M., are in fairly good agreement.
