“…The fracture mechanics of elastic-plastic model body was characterized by using the energy state equations. The aging of steel/aluminum SPR joints in salt spray environment was studied by Calabrese et al to evaluate their mechanical degradation in these critical environmental conditions [12]. The investigation was carried out on symmetrical or unsymmetrical joints at varying the total thicknesses.…”

“…Calabrese et al [15,16] recently conducted a long term salt spray corrosion test using steel/aluminium hybrid joints that were obtained via the SPR technique to evaluate mechanical degradation under these critical environmental conditions. The experimental results showed that the corrosion degradation phenomena significantly influenced both the performance and failure mechanisms of the joints.…”

The fatigue performances of self-piercing riveting (SPR) joints connecting similar and dissimilar sheets of TA1 titanium alloy (TA1), Al5052 aluminium alloy (Al5052) and H62 copper alloy (H62) were studied in this paper. The specimens of similar TA1 sheets treated with stress relief annealing were prepared to investigate the influence of relief annealing on the mechanical properties of SPR joints. Fatigue tests were conducted to characterize the fatigue lives and failure modes of the joints. Scanning electron microscopy (SEM) was employed to determine the fatigue failure mechanisms of the joints. The results showed that stress relief annealing has an apparent impact on the fatigue performances but has little influence on the static strengths of the joints. For SPR joints in similar or dissimilar sheets, joints between similar TA1 sheets possess the best fatigue resistance, which are significantly higher than the joints in dissimilar sheets. And most of the joints failed in the rivet and the locked sheet through fatigue tests, except the joints between TA1 and Al5052, which failed only in the locked sheets.

“…Recently, Calabrese et al [168] studied the influence of salt-spray on the joint strength of steel/aluminium hybrid SPR joints using the ASTM B117 standard. Overall, the joint strength degradation was more severe than that for aluminium SPR joints due to galvanic corrosion between the steel and aluminium sheets.…”

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.
