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,...

متن کاملPost-Tensioned Steel Connections Self-Centering Behavior Using the Finite Element Method
Due to lack of the proper and well behavior of steel moment-resisting connections subjected to the great and major earthquakes, excessive researches have been conducted to mitigate the damages on the primary elements and connections. Therefore, elimination of residual drift and increasing the plastic rotation capacity for the connectors in the panel zone are required. The main purpose of this s...
