WP 3: Constitutive models

WP 3 Goals

  • Develop constitutive equations tailored for residual stress prediction that capture the most relevant micro-structural effects in high strength steels.
  • Establish a reliable method by which the parameters in these constitutive equations can be experimentally identified and determined.

WP 3 Research challenges

  • Quantify phase changes and distribution during relevant temperature histories in the heat affected zone.
  • Quantify how the stress during plastic deformation depend upon the instantaneous phase distribution.
