Recently, the automobile industry has paid attention to multi-material structures for reducing the weight of vehicles. Determining the method for joining dissimilar materials is essential to realize the structures. Adhesive bonding can be applied to the joints among various types of materials. Therefore, adhesive bonding is considered as one of the joining methods for the structural parts consisting of dissimilar materials. On the other hand, strength design should be applied to assure the consistency of adhesive bonding structures. Structural analysis by finite element method (FEM) is often used for the strength design process. To improve accuracy of FEM, in this study, material models for FEM were studied. A continuum model was used for the material models. The parameters of the constitutive equation for the model were calculated from the results of cylindrical butt joining tests. Analytical results were also compared with experimental results, and the obtained material constitutive equation was verified.
