Abstract
We propose the methods to apply the EFGM (Element Free Galerkin Method) developed by T. Belytschko et al. to the stress analysis of Adhesive Butt Joints, and analyzed the interface stresses in the three-dimension. We divide the model of analysis to the domain of the same materials as Material1, Material2 and Adhesive, and applied the EFGM to Material1, Material2 and Adhesive respectively. Then, each displacement of Materiall and Material2 must be continuity on interface. So we restrain the displacements on the interface by the penalty method.
