  bibo_abstract:
  - The components of a body in white consist of many individual thin-walled sheet
    metal parts, which usually are manufactured in deep-drawing processes. In general,
    the conditions in a deep-drawing process change due to changing tribology conditions,
    varying degrees of spring back, or scattering material properties in the sheet
    blanks, which affects the resulting pre-strain. Mechanical joining processes,
    especially clinching, are influenced by these process-related pre-strains. The
    final geometric shape of a clinched joint is affected to a significant level by
    the prior material deformation when joining with constant process parameters.
    That leads to a change in the stiffness and force transmission in the clinched
    joint due to the different geometric dimensions, such as interlock, neck thickness
    and bottom thickness, which directly affect the load bearing capacity. Here, the
    influence of the pre-straining in the deep drawing process on the force distribution
    in clinch points in an automotive assembly is investigated by finite-element models
    numerically. In further studies, the results are implemented in an optimization
    tool for designing clinched components. The methodology starts with a pre-straining
    of metal sheets. This step is followed by 2D rotationally symmetric forming simulations
    of the joining process. The resulting mesh of each forming simulation is rotated
    and 3D models are obtained. The clinched joint solid model with pre-strains is
    used further to determine the joint stiffnesses. With the simulation of the same
    test set-up with an equivalent point-connector model, the equivalent stiffness
    for each pre-strain combination is determined. Simulations are performed on a
    clinched component to assess the influence of pre-strain and sheet thinning on
    the clinched joint loadings by using the equivalent stiffnesses. The investigations
    clearly show that for the selected component, the loadings at the clinch points
    are dependent on the sheet thinning and the stiffnesses due to pre-strain. The
    magnitude of the influence varies depending on the quantity considered. For example,
    the shear force is more sensitive to the joint stiffness than to the sheet thinning.</jats:p>@eng
