“…The traditional types of mechanical joints mainly include a single-lap joint, a double-lap joint, a single-strap butt joint and a double-strap butt joint. The single-strap butt joint is the main structure of wing panels, which are used as load-bearing components [9].…”

The self-piercing riveting (SPR) single-strap butt joints (butt joint) were fabricated in similar sheets of Al5052 aluminium alloy and 1420 aluminium-lithium alloy. Mechanical characteristics of SPR butt joints of different materials were discussed comparing with their corresponding SPR single-lap joints (lap joint). The effects of the rivet pitch and the strap length on the butt joints of different materials were investigated. Results indicated that the lap joints have better performance in strength and stiffness, while the butt joints have more superior shock resistance capacity. The strap length had some impact on the failure behaviour of the joint but not the joint strength. The load borne capacity of the butt joints was highly dependent on rivet pitch.

“…Kumar et al [13] conducted nonlinear finite element analysis on riveted lap joints and found that as long as the rivet did not yield, the load distribution between rivets was not uniform, which may lead to local high stress and cracking. Liu et al [14] numerically studied the residual stresses distribution of single-band butt joints with different rivet sizes and thicknesses. There is little research on the influence of gap between sheets on riveting quality.…”

Some controllable process parameters in the riveting process such as the gap between sheets, have an important impact on the quality of a riveted butt joint. In this paper, the finite element model of a riveted single-strap butt joint is established with the help of ABAQUS analysis software, and the riveting process is simulated under five kinds of gaps between sheets. From the perspectives of rivet upsetting size, rivet interference, radial deformation of sheet, and analysis of residual stress around the hole of sheet, the influence of the gap between sheets on the connection quality of the riveted butt joint is summarized. The results show that the left and right sheets will contact each other and there is extrusion stress between the sheets when the gap is zero. When the applied tensile load continues to increase, due to the influence of the secondary bending, the strap sheet responsible for the connection produces warping deformation, and there will be no further contact between the sheets. When the gap between sheets increases from 0 to 2 mm, the maximum deformation of strap sheets increases from 0.876 to 0.927 mm, which proves that the gap between sheets have no significant effect on the deformation of the strap sheet.
