An experimental study on clinched joints realized with different dies
Francesco Lambiase,A. Di Ilio +1 more
TL;DR: In this paper, an experimental investigation has been conducted on mechanically clinched joints, produced with fixed and extensible dies with different forming forces, and the results showed that the extensible die exhibited a similar strength as compared to those produced with the fixed die in single lap shear tests, while they are characterized by a higher strength when loaded during the peeling test because of a larger interlock.

Analysis of high temperature plastic behaviour and its relation with weldability in friction stir welding for aluminium alloys AA5083-H111 and AA6082-T6
TL;DR: In this paper, the influence of the plastic behavior of two aluminium alloys, very popular in welding construction, on friction stir weldability was analyzed. And the relationship between weldability, material flow during FSW and the plastic behaviour of the base materials, at different temperatures, was analyzed and compared.
