In the previous paper, the authors has dealt with the problem of adhesive joint under tension, and the effect of the adhesive thickness and material combinations on the strength of adhesive joint have been discussed. Using the FEM, it is has been explained explicitly that the strength of adhesive joint decreases with increasing of adhesive thickness under arbitrary material combinations. In this paper, the problem of adhesive joint under bending will be discussed using the FEM. Similarly, the effect of adhesive thickness and material combinations on the strength of adhesive joint will also be discussed. Comparing the results of tension and bending for the adhesive joint, the intensity of singular stress for the bending is larger than the intensity of singular stress for the tension for the most material combinations, although the intensity of singular stress for the bending is always smaller than intensity of singular stress for the tension for a bonded strip.
