In this study, we have suggested the new joint configuration, which has a curved surface at a bonded part, and we have named it an "adhesivel waved butt joint". FEM analyses to clarify the stress field at the bonded part were carried out. To confirm the reliability of the analytical results, experiments about strain distribution by using strain gauges were performed. In addition, effects of adhesive thickness and Young's modulus of adherends were examined. As a result, it was found that stress concentrations occur in center and edges at adhesive interfaces. Furthermore, the value of maximum stress increased as the adhesive thickness and Young's modulus of adherends increased. It was proved that the strain distribution by analytical result is consistent with that measured with strain gauges.
