    With increasing possibilities and demands for FEM predictions, there is a need to get each input right. For example friction modelling, press kinematics, tool deformations are issues that are addressed more and more. FEM simulations including these advanced models require that each piece of the puzzle must be right. Description of the accurate thermomechanical plasticity behaviour is important for these simulations because press and tool deformations, friction behaviour and crashworthiness are depending on having the right forces and temperatures in your system. This thermomechanical plasticity behaviour consists of strain rate and temperature dependent hardening curves and a yield locus to scale these hardening curves for the different deformation modes. An accurate and easy to use yield locus which can be determined from only three tensile tests is Vegter 2017.
