“…The validation of the DSSPR joining technology has been performed with tubular rivets of stainless steel AISI 304 and aluminium AA5754 sheets, to investigate the working principle and the geometric scalability of the tubular rivets. Recently, the chamfered ends of the rivets have been optimized to improve the rivet penetration and final morphology, and therefore increase the overall joint strength of the mechanical connection [ 17 ].…”

Double-sided self-pierce riveting (DSSPR) has been presenting itself as a proper alternative to self-pierce riveting (SPR) with many advantages for joining geometries of different thicknesses and cross-sections. To ensure its successful future industrial application, this paper presents a detailed comparison between different strategies to produce mechanical joints by means of the DSSPR process and discusses its performance and feasibility. Results show that the use of flat-bottom holes in both sheets provide interesting results, since they allow for a precise positioning of the tubular rivet in specific pre-defined locations, thus avoiding an incorrect joining procedure. This strategy tightens the tolerances of the process, while keeping a suitable level of destructive performance as demonstrated by the lap shear tests. Pre-riveting of the sheet has also been shown to produce suitable results in combination with or without a flat-bottom hole in the opposite sheet. This strategy comes at a cost of a slightly lower performance than that obtained with flat-bottom holes in both sheets, although the requirements of force and energy to complete the joining process are smaller. The conclusions of this research work are essential for selecting the joining strategy with DSSPR according to the requirements of the intended application.

Important developments have been achieved for self-pierce riveting with the utilization of a double-sided tubular rivet that is able to join sheets of similar and dissimilar materials with different and larger thicknesses, while remaining hidden in-between the sheets after the joining process is completed. Nevertheless, the performance of those joints can still be improved by an optimization of the rivet parameters, mainly the chamfered angle of the rivet ends and the ratio between the initial height and thickness of the rivet. In this paper, the correct parameter combination is established by the performance of the obtained joint to shear destructive tests, the requirements of force and energy, as well as the dimension of the protuberance produced above the sheets surface. The influence of the introduction of an additional rivet in the overall performance of the mechanical joint is also discussed. Joints of different thinner and thicker sheets are analysed, as well as the combination between those thicknesses, to extend the range of applications of the new joining by forming process.
