Abstract
Tensile-shear test, fatigue test and corrosion test are carried out on clinched joints of 6063-T5 aluminium alloy plate. From fatigue test, two different fatigue fracture morphologies which are base metal fracture and joint fracture are observed. The ratio of the plate width to the notch width (w/a) are used to classify the fracture morphologies and classification value are obtained. A tensile-shear test and a fatigue test are carried out about clinched joints exposed to SST1000h or CCT120 cycles. It is found that effect of corrosive environment on the static tensile-shear strength and fatigue strength of clinched joint is small.
