Self-piercing riveting (SPR) is widely used in multi-material structures; however, conventional rivet systems are limited ranges of material and sheet thickness. To address this limitation, Kappe et al. introduced versatile self-piercing riveting (V-SPR), which combines an extended punch actuator with a multi-range-capable rivet to enable joining of materials with tensile strengths up to 600 MPa without tool changes.\r\n                    <jats:sup>\r\n                      <jats:xref ref-type=\"bibr\">1</jats:xref>\r\n                    </jats:sup>\r\n                    This study presents a comparative investigation of a multi-range-capable rivet for V-SPR and conventional standard rivets in CP1000–aluminium and aluminium–aluminium joints. The analysis focuses on joint formation and mechanical performance under shear-tensile and cross-tensile loading. Metallographic cross-sections are used to characterise interlock formation, minimum die-side material thickness, and failure modes. Mechanical performance is evaluated using quasi-static tests, with emphasis on maximum load and failure mode. The experiments establish a demonstrated joinability matrix for the investigated sheet-thickness combinations using adapted punch and die motions. The results demonstrate the applicability of V-SPR to ultra-high-strength steel–aluminium and aluminium–aluminium joints. For the most industrially relevant combination investigated, St1.5–Al2.0 (CP1000–EN AW-6014), V-SPR achieves mechanical performance comparable to or higher than that of standard SPR while substantially reducing tool complexity through a single multi-range-capable rivet, a reduced die configuration, and fewer stack-specific changeovers. However, the independently driven inner and outer punches and active die increase actuator and control-system complexity.\r\n                  </jats:p>"}],"publication":"Proceedings of the Institution of Mechanical Engineers, Part L: Journal of Materials: Design and Applications","user_id":"44935","_id":"67569","publisher":"SAGE Publications","status":"public","quality_controlled":"1","project":[{"name":"TRR 285:  Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten","_id":"130"},{"_id":"133","name":"TRR 285 - Project Area C"},{"name":"TRR 285 - Subproject C02","_id":"146"}],"citation":{"ama":"Kaimann PK, Sarris J, Beck R, Bobbert M, Lechner M, Meschut G.
