  text: Modern industrial development has necessitated a wide range of joining technologies.
    Self-pierce riveting has become a prevalent technique for sheet metal assembly,
    especially in automotive applications. Achieving proper joint geometry and adequate
    load-bearing capacity depends on appropriate tool selection and precise process
    control. Material properties and condition also play a significant role in process
    performance. To accommodate the inevitable variations in component characteristics
    during production, a robust and stable joining process is essential. The study
    focuses on investigating the influence of preformed joining partners on the joining
    process and the joint's load capacity. An EN AW-6014 in T4 condition, as well
    as an HCT590X, are used as materials for this study. For this purpose, an exemplary
    process chain consisting of the steps of performing, joining, and shear load testing
    is studied. Each process step is implemented using an FE model to predict the
    outcome of subsequent steps. For analysis of the influence of pre-strain, an optimisation
    software is used to plan and execute variations of the process. These variations
    are used to create a meta-model that can describe the relationships between pre-forming
    and characteristic parameters of subsequent process steps. The resulting model
    is validated by comparing simulation and experimental data. Finally, in a novel
    approach, the robustness of the presented process chain is analyzed in terms of
    a tolerable performance level for the joining partners.

  text: Lightweight design is a driving concept in modern automotive engineering to
    minimize resource consumption over a vehicle's lifecycle through multi-material
    design, which relies on the use of joining techniques in car body fabrication.
    Multi-material design and the increasing trend towards producing large structural
    components using the megacasting process pose considerable challenges, particularly
    in the mechanical joining of aluminium-silicon (AlSi) castings. These castings
    typically exhibit low ductility and are prone to cracking when mechanically joined.
    Based on the excellent castability of hypoeutectic AlSi alloys, these are applied
    in sand casting and die casting as well as in megacasting. With a silicon content
    between 7 wt% and 12 wt%, these AlSi-alloys have a plate-like silicon phase that
    initiates cracks during mechanical joining. To enhance the joinability of castings,
    the research hypothesis is that improved solidification conditions enable a significant
    modification in the microstructure and therefore, increase the mechanical properties.
    During the manufacture of the castings using the sand casting process, the solidification
    conditions within the structural elements are varied to modify the microstructure
    to obtain castings with graded microstructure. The castings are evaluated using
    mechanical, microstructural and joining testing methods and finally, a microstructure-joinability
    correlation is established.
