“…To ensure efficiency, the springback of SPR joints during the tool (i.e., punch, blank-holder and die) releasing process was not simulated. More details about the FE model can be found in [38]. Other boundary conditions were kept consistent with those in experimental tests.…”

“…The prediction accuracies for the I 1 , t c and R out are 19%~29% higher than that for the t tip in joint 1-2. In previous research [38], this FE model had also been validated by comparing the experimental and simulation results of eleven joints within the same studied range, and the mean absolute error (MAE) for the I 1 , t c and t tip was 0.066 mm, 0.042 mm and 0.115 mm, respectively, and the corresponding mean absolute percentage error (MAPE) was 10.5%, 12.9% and 19.7%. Overall, the prediction result of the FE model for these joint quality indicators is accurate.…”

In this study, experimental and numerical investigations were carried out to achieve a comprehensive understanding of the impact of surface conditions on self-piercing riveting (SPR) joint quality. Oil lubrication and sandpaper grinding were employed in experimental tests to change surface conditions at rivet/top sheet, top/bottom sheets and bottom sheet/die interfaces. A finite element (FE) model for the SPR process was also adopted to numerically assess the impact of surface conditions. Variations in surface conditions were modelled by changing friction coefficients at contact interfaces. The results revealed that the friction coefficient between the rivet and top sheet (μ1) imposed significant influences on the interlock (I1) by affecting the deformation of the rivet shank and top sheet. The friction coefficient between the rivet and bottom sheet (μ2) showed a lower influence on the joint quality because of a smaller contact area and shorter interaction time. The friction coefficient between the top and bottom sheets (μ3) led to opposite changing trends of remaining bottom sheet thickness at the joint centre (tc) and under the rivet tip (ttip). The friction coefficient between the bottom sheet and die (μ4) demonstrated crucial influences on the remaining bottom sheet at the joint centre. The riveting force was significantly influenced throughout the whole riveting process by the μ1, but only affected at the end of the joining process by the other three friction coefficients.

“…Zhao et al studied the self-piercing rivet process of AA7075 sheets using different sheet thicknesses (1–2 mm) and ratios. The highest interlock ratio and inlet length were achieved by using a 6 mm rivet length at a sheet thickness ratio of 1.2 mm/1.8 mm [15]. Kim et al estimated the mechanical properties of different steel and aluminium sheet combinations joined with self-piercing riveting using a deep learning approach [16].…”

Self-piercing riveting (SPR) is a high-speed mechanical joining technique for sheet metal materials. In this study, the mechanical properties of DC04 steel and AA5182 aluminium alloy in triple combinations joined by the SPR method were investigated. For this purpose, triple-joining processes were performed in different combinations, and macro-structural analysis and tensile shear tests were carried out by comparing their mechanical properties. As a result of the study, the highest shear forces were obtained in FFA (DC04-DC04-AA5182) and AFF (AA5182-DC04-DC04) combinations. As the number of aluminium layers increases, the probability of tearing increases in triple joining. Higher spread ratios were generally measured under conditions with hard materials in the upper layers and soft materials in the lower layers.
