It is presently thought that, in riveting, plates are fastened by the rivet head, as well as by the pressure between the rivet axis side and plates in the rivet hole as a result of the spreading of the rivet axis. However, the fundamental characteristics of these joint forces have not been clarified yet. Therefore, to set guidelines for obtaining a high joint strength in riveting, we examined the fastening force for plates by the rivet head and the joint force between the rivet axis and plates by carrying out experiments such as separation and rotation tests on joined plates, push-out tests on the rivet axis side, and the elastic-plastic FEM simulation of riveting in the case in which the rivet material is much softer than the riveted plate. The results show that, in such a case, the fastening force for the plates by the rivet head is very small, so that the plates are primarily joined on the rivet axis side. The relationships of punch shape with springback of rivet and joint force on the rivet axis side were also obtained from these results.
