  • Uses specific material parameters calculated from tensile and torsion tests.
  • Manufacturing effects can be accounted for by using equivalent plastic strain in the unloaded component.
  • Can take into account the cut edge effect on thin sheet material
  • Includes new optimised and spot weld methods.
