The join-ability and energy absorption of extensible die clinched joints in titanium and aluminum-lithium sheet materials were investigated in this paper. Tensile-shear tests were carried out to characterize the mechanical properties of different clinched joints made of the similar and dissimilar alloy sheets combinations. The quality assessment, load-bearing capacity and energy absorption of different clinched joints were studied. Results showed that the load-bearing capacity and energy absorption of clinched joints with titanium as upper sheets are higher than that of the clinched joints with aluminum-lithium as upper sheets.
