Fatigue of self-piercing riveted joints in aluminum alloy 6111

Self-piercing riveting (SPR) is becoming an important joining technique for the automotive applications of aluminum sheets. In this paper, the fatigue behavior of self-piercing riveted joints in 6111-T4 aluminum sheets is studied. Both constant amplitude fatigue tests as well as two-level cumulative fatigue tests are performed. It is observed that the rivet setting pressure, which is one of the key process parameters, influences the static...
