  - The growing demands of resource-saving processes and products are leading to increasing
    importance of lightweight construction for the automotive industry. One approach
    is multi-material design, which uses high-strength steels and aluminium alloys
    in the production of vehicle bodies. Therefore, reliable processes for joining
    components with different mechanical properties and geometries are necessary.
    As conventional joining processes reach their limits, new versatile processes
    and methods are required which can adapt to different process conditions and disturbance
    variables. A widely used joining process to join different materials is self-piercing
    riveting as a joining by forming method, however it is characterised as inflexible
    to changing process conditions due to a linear process kinematic and rigid dies.
    An approach to extend the process limits is the application of a tumbling kinematic
    for the punch. Thus, an adapted tumbling strategy can be used to influence the
    joining process and to achieve a controlled material flow in order to manufacture
    tailored joints. For the fundamental investigation of the process, numerical investigations
    are necessary. In order to achieve high model quality a precise material modelling
    is crucial. Therefore, a characterisation of the materials HCT590X+Z and EN AW-6014
    as typical materials of multi-material mixes and the rivet material 38B2 is performed.
    Due to the different stress conditions during tumbling self-piercing riveting
    suitable characterisation methods are selected and carried out.@eng
