WP 1: Integrity assessment

 WP 1 Goal

  • Develop a novel procedure for structural integrity assessment based on quantitative modelling of residual stresses and associated changes in the microstructure and mechanical properties of the material.

WP 1 Research challenges

  • Define a crack driving force in a welded steel component in which there is a residual stress field in addition to the external loads.
  • Establish reliable fracture criteria and failure mechanisms associated with this crack driving force.
