Outline of Final Research Achievements

A joining method having a functional flat surface without concavo-convex surface caused by a plastic joining method such as a self piercing rivet method or a mechanical clinching method was made possible by the plate forging joining method. With a perfectly flat structure, weak bonding strength of 95 N was achieved, but bonding strength exceeding 2 kN could be achieved with plate forging joining with small flanges. This plate forging joining method is a lap joining method, the larger the difference in strength between the two sheets is, the more effective joining method is, which is greatly different from the conventional plastic joining method.
