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 "adhesively waved butt joint". Mechanical properties in some present joints subjected to static tensile load were analyzed, using finite element method. FEM analyses to clarify the stress field at the bonded part were carried out. We have investigated specially in focus joint named "double-waved butt one". To confirm the reliability of the analytical results, experiments about strain distribution by using strain gauges were performed. As a result, it was found that stress concentrations occur at both edges of adhesive interfaces. Furthermore, the value of maximum stress decreased as wave number at bonded part increased. It was proved that the strain distribution by analytical result is consistent with that measured with strain gauges.
