Joinability of aluminium alloy and mild steel sheets by self piercing rivet

Effect of Process Parameters on Tensile Strength of Friction Stir Welded Joint of Pure Copper

“…Friction stir welding was using commercially successfully from the early years of 21 st century and evolve the world of metal joining of aluminium industry. The friction stir welding is also considered as the green welding technique because of its less energy consumption and lower heat generation during welding [4]. Technically, friction stir welding process is very simple and easy to understand.…”

Recent development in finite element analysis of self-piercing riveted joints

“…Numerical simulation may provide a means to overcoming these problems. Abe et al [41] evaluated the SPR joinability of aluminum alloy and mild steel sheets through FE simulations and experiments. Defects in the riveting were categorized into the penetration through the lower sheet, the necking of the lower sheet, and the separation of sheets to obtain optimum joining conditions.…”

Numerical simulation of self-piercing riveting process (SRP) using continuum damage mechanics modelling

“…The necking of the lower sheet is a thinning phenomenon, similar to the penetration defect. In the separation of the sheets, the spread of the leg of the rivet is too small to join the sheets, and the riveted sheets are easily separated [5]. A sketch of these defects is shown in Fig.…”

“…steel and aluminum), this ability seems to depends on the ratio between the upper and the lower sheets thickness. For steel-aluminum it was found that penetration, necking and separation are caused by small total thickness, small thickness of the lower sheet and large total thickness, respectively [5]. The possibility to predict the occurrence of such defects by means of numerical simulation relies mainly in the ability to model plastic deformation in the materials and the capability to predict the occurrence of fracture phenomena.…”
