Study on Clinching of Titanium Alloy

Adopting experimental method to examine clinching is able to apply to the joining of similar titanium alloy in this study. Also, to use tensile-shear test to figure out mechanical properties of clinched joints to TA1-TA1 clinched joints and Al5052-Al5052 clinched joints. The results show that average load of Al5052-Al5052 clinched joints is largely lower than average load of TA1-TA1 clinched joints. Average load of TA1-TA1 is around 4427.58, equal to 3.55 times to Al5052-Al5052.The two types of fractured joints are all neck shear fracture of the upper sheets. Therefore, the strength of joints is dependant to the strength of the material. And average displacement of TA1-TA1 clinched joints is higher than that of Al5052-Al5052 clinched joints.
