  text: In the development of advanced lightweight automotive solutions, self-piercing
    riveting (SPR) offers the possibility of joining multi-material structures to
    fulfil a wide variety of requirements. 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>

  text: The present study is an experimental analysis of the influence of pre-forming
    on the failure behaviour of clinched specimens under quasi-static and cyclic loading
    conditions. In this context, the geometric formation of the clinched joints is
    taken into account, with regard to the loading behaviour. The study also includes
    a comparison of the failure behaviour of quasi-static and cyclic tested specimen.
    Testing is done on non-pre-deformed and pre-deformed specimens. For this purpose,
    experimental investigations are carried out on two material combinations consisting
    of HCT590X steel sheet and EN AW-6014 T4 aluminium sheet. 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. The investigations show that the cyclic load-bearing
    behaviour of the HCT590X joints is reduced by introducing a plastic pre-deformation
    of the to be joined parts.</jats:p>

  text: This study focuses on damage modeling across different mechanical joining
    processes within a process chain, specifically using clinching and self-pierce
    riveting (SPR). The aim is to apply a comprehensive model that captures the damage
    mechanisms and interactions in these technologies, optimizing them for enhanced
    performance and durability of aluminum joints. A GISSMO damage model was utilized,
    based on the stress states occurring during the joining process and a newly introduced
    damage testing method. This model was applied to both clinching and SPR processes.
    A detailed analysis of the stress states provided insights into their effect on
    the material. By incorporating these insights into the GISSMO model, improved
    accuracy in damage prediction was achieved. The model's application to clinching
    and SPR demonstrated its effectiveness in optimizing aluminum joint performance
    and durability, ensuring that the processes can be finely tuned to minimize damage
    and enhance joint quality.</jats:p>
