“…To improve the capability of the SPR process, Iguchi and Ohmi [61] designed a die that has the capability to join a thick sheet to a thin and less ductile sheet as the bottom material. By using a spring-loaded sliding pin in the centre of the die, the excess denting of the top thick sheet could be prevented and the penetration of rivet into the bottom sheet was increased, as shown in Fig.…”

“…Westgate et al [45] developed a lightweight deep-throat Cframe for an early robot-mounted hydraulic SPR system. An SPR process with a die with a spring-loaded sliding pin at the bottom of the cavity [61] Nowadays, electric-servo SPR systems are preferred, which are much lighter than hydraulic SPR systems and can also eliminate the need for connections to high pressure hoses. As a result, the requirement on the weight of the C-frame is reduced and the automation of the SPR process becomes easier and less costly.…”

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.

“…The following are the results: (1) Although the stiffnesses of the SPR specimens were similar in experiments, the fatigue life varied with sheet material and thickness combination. (2) The aluminum-aluminum SPR specimen showed the lowest stiffness, unlike the aluminum-steel specimen which showed the highest stiffness. (3) Even though the SPR specimens had similar stiffness, fatigue life between the specimens was significantly different in the experiments.…”

“…Operating strength affected by defects such as fume and spatter, which could compromise the safety and cleanness of the working environment, are a quality concern. On the contrary, SPR is a relatively quiet process that does not produce fume and/or spatter, and requires less power than conventional techniques [1][2][3][4]. SPR has many advantages such as high-energy efficiency, bond simplicity between heterogeneous materials, and no thermal defect in the welding region compared with conventional techniques.…”

The highest structural stiffness of an SPR joint was exhibited in the specimen constituted with 5J32 and ASPH, and the lowest stiffness in that constituted with the single 5J32 combination. Even though the structural stiffness of an SPR joint specimen is roughly the same with another type of joint, the fatigue life is different according to sheet material and its thickness. The results of numerical analysis are nearly identical to those of experiments. Thus, it can be that FEM modeling in accordance with FEMFAT is effective in assessing the stiffness and fatigue life of SPR joints, and can be an alternative to experimental analysis.
