(2007)]. These A three-step computational approach is proposed to help studies are focused mainly on the following aspects of establish the effect of various self-piercing riveting (SPR) this process: (a) an investigation of the effect of various process and material parameters on the quality and the process parameters such as rivet shape/material, mechanical performance of the resulting SPR joints. Using worksheet materials and thicknesses, die shape, the results of a virtual-testing procedure, the constitutive clamping force, punch force vs. time profile, etc. on the relations for the simplified SPR connectors are determined, overall structural integrity of the resulting joint; (b) parameterized and validated. The availability of such mechanical testing of the joints to determine their connectors is mandatory in large-scale computational static, dynamic and cycling strengths under various analyses of whole-vehicle crash.
