Aluminium Alloy Self-Pierce Riveting for Joining of

For the joining of aluminium alloy sheet by the aluminium rivets, the joinability was improved by the designed shape of the rivet and die. To pierce the upper sheet, the diameter and edge angle of the rivet are modified. The diameter of the depth and the cavity of the die were also designed from trial and error using finite element simulation.sp.info Self-piercing riveting connections using aluminium rivets(2006) have conducted a study on the joinability between mild steel and aluminium alloy sheets; these authors have also suc-ceeded to use the SPR process for joining high strength steel and aluminium sheets with a steel rivet (Abe et al., 2008). Optimum joining conditions have been obtained for a conventional rivetsp.info Improvement of Joinability in Mechanical Clinching of aluminium alloy sheets joined by mechanical clinching. Abe et al. (2014) showed that the fatigue strength of ultra-high strength steel sheets increases by mechanical clinching. The mechanical clinching of the ultra-high strength steel sheets having low ductility is not easy although Varis (2002, 2003) has joined the high strength steel sheets.sp.info 10.1016/j.jmatprotec.2011.11.015 DeepDyveJun 11, 2020 · In the mechanical clinching of high strength steel and aluminium alloy sheets, the authors ( Abe et al., 2007b ) showed the high strength steel sheet tends to fracture because of small ductility, and thus the combination of sheets is limited still.

In the present paper, high strength steel and aluminium alloy sheets were joined by the
