The purpose of this study is to investigate the failure mode dependent the load bearing characteristics of the mechanical clinching under the mixed mode loading condition. The joint strength of the mechanical clinched joint was determined by the geometrical interlocking shape parameters, such as the neck thickness and undercut. The load bearing tests under the pure normal and shear mode loading condition were carried out to investigate the influence of the geometrical interlocking shape parameters on the failure mode of the mechanical clinching and its joint strength by analytical approach. The Arcan test apparatus was modified to realize the mixed mode loading condition on the cross-tension specimen. For each angular positions(α=0,15,30,45,60,75,90° ), the failure mode and strength of the mechanical clinched joint was evaluated by the cross tension specimen with the modified Arcan test apparatus. Based on the experimental result, an analytical expression was derived to describe the joint failure criterion under the mixed mode loading condition.
