A Performance Study of Clinched Joints with Different Material

Abstract:

Clinching is a high-speed mechanical fastening technique for point joining of sheet material. In order to investigate the influence of material property on the mechanical property and failure mode of clinched joints, three types of clinched joints in aluminum alloy sheet were tested under tension-shear loading with MTS landmark, separately. Results showed that the property of the substrate had effective on the performance of clinched joints. Clinched joints had higher strength and good energy absorption capacity when the strength of the substrate was higher. The strength and energy absorption capacity of the clinched joints were evaluated via load-displacement curves. While the failure modes of clinched joints were all the same: neck facture failure.
