The mechanical joining technologies haveincreasingly reached their process limits incombination with aluminum alloys and ultrahigh strength steels. During this study theshear clinching technology is developed inorder to extend the previous process limitsof mechanical joining for composite designconnections in combination with ultra highstrength steels. Compared to establishedjoining technologies, the new clinching processworks without any additional joiningparts or upstream process steps, such aspre-punching operations. The numericaland experimental tests of this study create abasic understanding of how the processworks and the potential for using cut clinching.
