Abstract

This paper deals with a two-dimensional stress analysis of adhesive butt joints subjected to tear loads. The purpose of the present paper is to contribute to an establishment of the fracture criteria of joints. Similar adherends and an adhesive bond are replaced with finite strips in the analysis. Stress distributions in adhesive joints are analyzed by using the two-dimensional theory of elasticity. The effects of the ratio of Young's modulus of adherends to that of the adhesive and the thickness of adhesive bonds on the stress distributions are shown by numerical computations. For verification, experiments are performed with respect to the strain of adherends. The analytical results are in fairly good agreement with the experimental ones.
