“…The fatigue test results of the CFRP to aluminium 6111 T82 SPR lap-shear specimens also displayed a large scatter in fatigue life as the maximum fatigue load approached the maximum quasi-static load (3857 N). A similar scatter in fatigue life was also reported elsewhere in studies performed on SPR in composite to aluminum alloys [1,21,23]. This scatter in fatigue life close to maximum static load may be due to the scatter in the quasi-static behavior of the joints, which is suggested in Figure 3.…”

“…In several studies of metal-to-metal SPR lap-shear joints, fretting has been observed to be one of the dominant causes for crack initiation and significantly accelerated the crack growth in these SPR lap-shear joints [8,10,[28][29][30]. Even though fretting was also observed in SPR lap-shear joints of aluminum to glass-fiber reinforced thermoplastic composite [23], no traces of fretting were observed in any of the SPR lap-shear test specimens tested in this study. Absence of fretting in this study may be attributed to the presence of a thin layer of CFRP sandwiched between the interfaces of the rivet and the aluminum sheet, as seen in Figure 2(b) and 2(c).…”

“…In this study, the rivet head entered the top CFRP laminate and damaged the top carbon fiber ply leading to the pull-out of the CFRP panel. This type of failure, where the top fiber reinforced composite panel fails due to the damage induced in the laminate by cutting of fibers, is generally referred to as the bearing failure [1,23]. …”

“…Therefore, it is feasible to use this technique when joining polymer-based fiber reinforced composite materials. Studies have shown that SPR technique can be effectively used in joining fiber reinforced composites to metals like steels [19] and aluminum alloys [1,[20][21][22][23][24]. A majority of the studies on SPR in fiber-reinforced composites to metals focus on the influence of the process parameters on joint quality, including die geometry [25], distance between rivets [21], and oil pressure in the riveting system [1,26,27].…”

“…A majority of the studies on SPR in fiber-reinforced composites to metals focus on the influence of the process parameters on joint quality, including die geometry [25], distance between rivets [21], and oil pressure in the riveting system [1,26,27]. Very few studies have been conducted on the fatigue performance of SPR in composite to metal joints [1,21,23]. During the SPR process, the piercing of rivets through the composite panel causes localized damage by cutting the fibers; it also brings about deformation of the bottom aluminum sheet which results in a stress concentration and causes local changes in the material properties around the rivet shank.…”

Numerical simulation and experimental validation of self-piercing riveting (SPR) of 6xxx aluminium alloys for automotive applications F Hönsch, J Domitner, C Sommitsch et al. Abstract. In this study, the tensile and fatigue behaviour of self-piercing rivets (SPRs) in carbon fibre reinforced plastic (CFRP) to aluminium 6111 T82 alloys were evaluated. An average maximum lap-shear tensile load capacity of 3858 N was achieved, which is comparable to metal-to-metal SPR lap-shear joints. The CFRP-Al SPRs failed in lap-shear tension due to pull-out of the rivet head from the CFRP upper sheet. The CFRP-Al SPR lapshear specimens exhibited superior fatigue life compared to previously studied aluminium-toaluminium SPR lap-shear joints. The SPR lap-shear joints under fatigue loads failed predominantly due to kinked crack growth along the width of the bottom aluminium sheet. The fatigue cracks initiated in the plastically deformed region of the aluminium sheet close to the rivet shank in the rivet-sheet interlock region. Scatter in fatigue life and failure modes was observed in SPR lap-shear specimens tested close to maximum tensile load.

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.
