This paper presents the strength analysis of joining by clinching for various values of parameter X of the bottom thickness. The maximum joint strength was obtained by performing lap joints, H-shaped samples and T-shaped samples strength test. For the specified value X of the bottom thickness, a test bar of clinching joints was also subjected to complex stress state until destruction. Thus, the impact of joint load direction on the maximum load capacity was determined. The effect of radial clearance between the die and the punch on the forming process, shearing and tearing was also obtained. Moreover, the paper contains an example of new sheet metal joining technology using rivets (ClinchRivet). The complex load tests results of the rivet joints were compared with those obtained for clinching.read more

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.
