With regard to the entire process chain, production-related pre-deformations of the parts to be joined can influence the geometric shape and load capacity of SPR joints. Various studies have investigated the influence of pre-stretched sheet materials, in the sense of pre-drawing processes, on the formation of SPR joints. The impact of pre-stretching sheet metals on the formation of their geometrical characteristics and the shear-tensile strength of SPR processes was observed [1]. Pre-rolled semi-finished products are also joined together in mixed material automotive structures, e.g. tailor rolled blanks. This work aims to investigate the influence of pre-rolled joining parts on the geometric formation and load-carrying capacity of SPR joints. For this purpose, sheets of metal are cold-formed using a rolling process to induce a defined strain-hardening state in the material and then joined in various combinations. As the degree of deformation increases, the rolling of samples can lead to minimal accumulation of damage in the sheet materials, which can influence the joint behaviour. The rolling process, as well as the subsequent joining process, are also investigated by FEM. The influence of pre-rolled semi-finished products on the strength of the SPR joints is investigated.</jats:p>","lang":"eng"}],"publication":"Materials Research Proceedings","type":"conference"},{"intvolume":"        52","citation":{"bibtex":"@inproceedings{Schlichter_Harabati_Böhnke_Bielak_Bobbert_Meschut_2025, title={Investigation on manufacturing-induced pre-deformation on the fatigue behaviour of clinched joints}, volume={52}, DOI={<a href=\"https://doi.org/10.21741/9781644903551-16\">10.21741/9781644903551-16</a>}, booktitle={Materials Research Proceedings}, publisher={Materials Research Forum LLC}, author={Schlichter, Malte Christian and Harabati, Özcan and Böhnke, Max and Bielak, Christian Roman and Bobbert, Mathias and Meschut, Gerson}, year={2025} }","short":"M.C.

The focus is on the fatigue analysis of the clinched joints. The aim is to identify the failure modes under cyclic loading and the crack formation with regard to forming operations prior to the joining process.
