Abstract
The present disclosure relates a rivet body, including a rivet head and a rivet shank, composed of a different material than a mandrel used for insertion into a workpiece(s), the mandrel including a mandrel shaft and a mandrel cap. The rivet body receives the mandrel shaft, including the mandrel cap, through the rivet shank. The mandrel shaft is received by the installation tool, which rotates the rivet body, and the mandrel cap locally deforms workpieces(s) through friction riveting to install the rivet body. During the friction riveting, the fast-rotating rivet body is pushed into the workpiece(s) causing local deformation/melting where the mandrel cap contacts the workpiece(s). The mandrel cap creates a cavity which progresses through an upper surface and a lower surface of the workpiece(s).
