“…a-c from the same joint after the fatigue with maximum load of 0.7 kN; d from a specimen after the fatigue with maximum load of 1.8 kN. The marked areas were ductile failure areas by the static test [95] to carry loads, whereas parts subjected to dynamic impact must also be designed to absorb energy [144]. It is believed that the dynamic performance of a joint, especially a mechanically fastened joint, will be different from that of a single material, because of the existence of complex structures and stress concentrations in the joint.…”

“…Some research demonstrated that the high test speeds during dynamic tests could increase the joint strength. Sun and Khaleel [144] studied the dynamic performance of 13 different joints with aluminium alloys or aluminium alloys and steels joined by SPR and RSW. The loading rates they used were quasi-static, 4.47 and 8.94 m/s.…”

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.

“…In Sun and Khaleel [26] studied the dynamic strength for SPR joint made of heterogeneous sheet and they found that the dynamic strength increased with increase of loading rate. To research the influence of loading rate against the strength of SPR connections, the tensile tests with various loading rates were done on 1.5 mm thick cold-formed thin-walled steel connections.…”

The paper presents an experimental investigation on the shear strength of self-piercing rivet connections used in thin-walled steel structures. The test program included specimen variations in the number of rivets in each connection, rivet spacing, end distance, and steel sheet thickness. According to the experimental results, the curve of load-slip, peak load, and failure mechanism for all specimens were analyzed. Parameters of riveting in terms of end distance, spacing, arrangement, length, and thickness difference between connection components were studied on their effects for shearing performances of self-piercing rivet connections. A design method based on the model of transmission dynamics of infectious diseases was proposed for calculating the shear strength of the rivet connections. The strength reduction due to the effect of group rivets was considered in the new method.ii

“…Sun and Khaleel (2005) investigated the quasi-static behaviour of SPR connections using cross-shaped tension specimens. This work was extended to also include dynamic testing (Sun and Khaleel, 2007). Similar and dissimilar materials were joined, and tests were carried out using cross tension, lap-shear and peeling specimens.…”

Force-displacement responses and failure behaviour of connections using flow-drill screws to join aluminium sheets were investigated under various quasi-static loading conditions. This included single connector tests under tensile, shear and combined tensile and shear loadings, using cross test coupons in a new test set-up, and peeling and single lap-joint tests. The strength of the connection increased with the amount of shear loading, while the ductility decreased. No effect of the anisotropy of the sheets on the behaviour in the single connector tests was found. Axial crushing tests of aluminium single-hat sections joined with flow-drill screws were also performed. Two connection failure modes not observed during the single connector test were found in these tests.For comparison, equivalent single connector and component tests were carried out for self-piercing rivet connections. Similar trends with respect to the ductility, maximum force and shape of forcedisplacement curves were observed for the two connections, but the local failure modes were different.
