“…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.…”

“…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.

“…For mechanical joining with screws and rivets, pre-drilling operations are needed and stress concentration appears around edges of holes. Thus, joining by mechanical clinching for certain parts of the vehicle body are widely applicable, especially when joining two different materials [1]. Mechanical clinching initially using cutting and upsetting of sheets with rectangular tools [2]; then improved to become a joining process using an interlock without cutting [3].…”

Abstract-In this study, a thin aluminum sheet are to be joined by mechanical clinching. The diameter of the die and stroke of the punch are controlled whereas the thickness of the sheets, diameter of the punch and speed of the machine are fixed in order to obtain the best results. It was found that mechanical clinching has superior fatigue strength due to the large yield stress of the sheets and relaxation of the stress concentration. The interlocking between the sheets, the thinning of the sheet and the fracture were observed.

“…A simplified failure map of the failure mechanisms and the effect of the corrosion were drawn. Di Franco et al's paper [14] investigated the influence of the distance between rivets in SPR joints made of aluminum blanks and carbon fiber composite panels (Al/CFRP). The latter find applications in various fields of naval and land transportation industries.…”

Self-piercing riveting is a relatively new high-speed mechanical joining technique. The present paper deals with the join-ability of similar and dissimilar titanium sheets by self-piercing riveting and the mechanical properties of the self-piercing riveted joints. Tensile-shear tests were carried out to characterize the mechanical properties of different self-piercing riveted joints made of the similar titanium sheets and the dissimilar metal sheet combinations. The normal hypothesis tests were performed to examine the rationality of the test data. The load-bearing capacity, energy absorption, and failure modes of different titanium sheet self-piercing riveted joints were studied. Results showed that the load-bearing capacity of self-piercing riveted joints with titanium as upper sheets are higher than that of the self-piercing riveted joints with titanium as lower sheets.
