In this report, adhesive strength criteria and testing methods were investigated experimentally and analytically. Both the cylindrical butt joint specimen with various angle of interface edge subjected to the combined tensile with torsional loading and the lap joint specimen were used for the experiments. Temperature and loading rate dependency was also investigated. Principal stress, strain and Mises stress distributions at the adhesive interface of these specimens under the critical load were obtained by the elastic-plastic finite element analysis using MARC. As a result, the Mises stress was found to be the most dominant factor of adhesive strength for a hard adhesion, but the principal stress for a elastic adhesion and the torsion test of the round bar butt joint was the best testing method for various types of adhesive joints.
