Clinching of similar and dissimilar sheet materials of galvanized steel, aluminium alloy and titanium alloy

Abstract

Aimed to describe the clinching join-abilities of galvanized steel with aluminium alloy and titanium alloy, extensible die clinched joints were prepared for similar and dissimilar sheet materials combinations. The quality of the clinched joints was analysed from the aspects of material forming, load-bearing capacity and failure modes. The failure mechanism of the clinched joints was researched from macroscopic and microscopic aspects. The results show that the sheet materials which have better strength and hardness, are suitable to be used as upper sheets in the clinching process.
