  - In this study, an innovative friction model is used to improve the quality of
    clinching process simulations. Consequently, the future over dimensioning can
    be reduced. Furthermore, the improved prediction quality of the joining process
    simulation leads to an improvement in the simulation of load-bearing capacity
    as well. In this way, the entire sampling process can be performed virtually without
    any experimental investigations. This will contribute to the advancement of lightweight
    construction in the automotive industry. In this work, the frictional behavior
    is studied in dependence on the local joining process parameters. As a reference
    for the numerical investigations, clinch joints by means of a die with fixed geometry
    are joined. Additionally, a hardness mapping is performed on the microsection
    of the clinch joints. It shows the local strain hardening, which correlates with
    the forming degree in the simulation. Based on the occurring contacts and the
    local joining process parameters in the joining process simulation, the test matrix
    for the experimental friction tests is defined. The friction tests are carried
    out on a compression-torsion-tribometer. This type of tribometer is able to apply
    high interface pressures above the initial yield stress due to the specimen encapsulation.
    Besides, the pure joining part contact, the contact between the joining part and
    joining tool can be tested as well. The experimental test setup offers the possibility
    to evaluate the influences of temperature, relative velocity, interface pressure,
    and frictional stroke independently. Based on the results of the experimental
    friction tests, a friction model is created. The resulting friction model is integrated
    into the numerical joining process simulation via a subroutine. To validate the
    quality of the new friction modeling, the results of simulations are compared
    with the experiments in terms of load-stroke diagrams, joint geometry, and hardness
    mappings on the microsection. </jats:p>@eng
