Fretting wear in self-piercing riveted aluminium alloy sheet

Fretting wear in aluminium alloy AA5754 joined by self-pierce riveting (SPR), a relatively new fastening technique increasingly used in vehicle structures, has been investigated in this paper. Surface damages have been induced when a joint experienced a sinusoidal cyclic tension–tension load. Various degradation zones have been characterised in the contact surfaces between the aluminium sheets, as well as the rivet and the locked sheet....
