The sleeve riveting is a mechanical fastening method of the two or three plate parts with the bolt and the nut formed from a sleeve by the swaging punch. Sufficient material flow to the tooth part of a bolt should be achieved in the sleeve by the punch movement for successful fastening. We carried out a series of physical simulation of the sleeve riveting process represented by the two dimensional physical model, and the material flow and plane strain deformation of the sleeve in the riveting process could be observed and measured. We examined three types of punch head ; i.e. ; the tapered corner head with slant angle 10 or 15 degrees and the round corner head, and measured the punch load-stroke curves and calculated the filling conditions of the sleeve to the tooth part of a bolt. Then, sufficient information to determine optimum configuration of the punch head could be obtained by the present investigation.
