  text: Sheet metal forming as well as mechanical joining demand increasingly accurate
    and efficient material modelling to capture large deformations, the inherent sheet
    orthotropy and even process-induced damage, which is expected to be influential.
    To account for large strains the additive logarithmic strain space is utilised
    that enables a straightforward incorporation of plastic anisotropy, herein modelled
    by a Hill48 yield function. A gradient-enhancement is used to equip the ductile
    damage model with an internal length scale curing the damage-induced localisation.
    An affine combination of the local and non-local softening variable is derived
    enabling a more efficient single surface formulation for the regularised plasticity-damage
    material model.
