Abstract
To explore the failure principle of single-point butt clinched joints, the AA5052 and AA6061 sheets were employed to produce the single-point butt clinched joints. The microscopic morphology of the fracture surface, geometrical parameters, static strength, energy absorption and failure details of the joints were analysed. The experimental results showed that fracture forms of sheet materials are the same as ductile fracture. The sheet combination has a significant influence on the mechanical properties of the single-point butt clinched joint, which is ultimately due to the different mechanical properties of the basal sheets. The single-point butt clinching process proposed in this work contributes to simplifying the clinching process while increasing the joining efficiency.
