“…However, for T-peel fatigue with a high maximum load, such as 1.8 kN, due to the geometry change through large plastic deformations, there was a large stiffness increase at the beginning of the fatigue. Similar results have been reported by Agrawal et al [129] when they studied the development of specimen stiffness during lap shear fatigue using the specimens with 2-mm aluminium alloy joined to 2-mm aluminium alloy.…”

Self-piercing riveting (SPR) is a cold mechanical joining process used to join two or more sheets of materials by driving a rivet piercing through the top sheet or the top and middle sheets and subsequently lock into the bottom sheet under the guidance of a suitable die. SPR is currently the main joining method for aluminium and mixed-material lightweight automotive structures. SPR was originated half century ago, but it only had significant progress in the last 25 years due to the requirement of joining lightweight materials, such as aluminium alloy structures, aluminium-steel structures and other mixed-material structures, from the automotive industry. Compared with other conventional joining methods, SPR has many advantages including no pre-drilled holes required, no fume, no spark and low noise, no surface treatment required, ability to join multi-layer materials and mixed materials and ability to produce joints with high static and fatigue strengths. In this paper, research investigations that have been conducted on self-piercing riveting will be extensively reviewed. The current state and development of SPR process is reviewed and the influence of the key process parameters on joint quality is discussed. The mechanical properties of SPR joints, the corrosion behaviour of SPR joints, the distortion of SPR joints and the simulation of SPR process and joint performance are reviewed. Developing reliable simulation methods for SPR process and joint performance to reduce the need of physical testing has been identified as one of the main challenges.

“…Self-piercing riveting (SPR) is receiving more recognition as a possible and effective solution to join body panels and structures [10][11][12][13][14]. For example self-piercing riveting is still the first choice for most well-known automotive car industries when considering the intensive use of aluminum alloy.…”

“…All agree that the fatigue strength of SPR joints is superior to that of the spot-welded joints (Henrob Group, 2007;Mallick, 2001, 2003;Razmjoo and Westgate, 1999;Krause and Cherenkoff, 1995;Bonde and Grange-Jansson, 1996;Booth et al, 2000;Cai et al, 2005;Hahn et al, 1999;Sunday, 1983;Bonde, 1995;Litherland, 1998;Tileli et al, 1999;Li and Fatemi, 2006;Agrawal et al, 2003).
