Therefore, these variations can contribute significantly to the scatter of fatigue properties obtained on specimens without stress relief, especially at low stress intensity factor range. To address this problem, a new compliance-based method is developed for correcting fatigue crack growth data in the presence of a residual stress fields of variable magnitude. It is based on the theoretical modelling of the propagation of an edge crack in an elasto-plastic material subjected to cyclic loading of a constant amplitude. The method is demonstrated for compact tension super duplex stainless steel (SDSS) specimens fabricated using wire-arc additive manufacturing (WAAM) and tested without post-fabrication heat treatment. It can be applied for both the evaluation of residual stress fields in fatigue specimens and obtaining the intrinsic fatigue properties of materials.
