Abstract:

Joining process and mechanical properties of clinched joints in Al5052 aluminum alloy sheets had been studied in this study. The clinched joints were classified to round one and rectangle one. Results of cross-section showed that the minimum thickness of the rectangle joints were lower than the round joints, and the aspect ratio of undercut section corresponding was larger. The strength of rectangular joint was 1.7 times of round one. Failure mode of rounded joint was the upper sheet fractures at the neck having a minimum thickness, but failure mode was the mix of neck-fracture and pulled-out for rectangular joint.
