The objective of this study is to provide a three-dimensional predictive numerical tool of the evolution of the curvature the crack front during the propagation of a fatigue crack, taking into account the plasticity induced crack closure. Targeted testing performed on a CT-50 austenitic 304L stainless steel specimen monitored the stabilized crack front shape for a long crack for different load ratios R and different amplitudes ΔK of the stress intensity factor (FIC). In order to avoid any influence of the loading history, a constant value of ΔK has been applied. A 3D model, using ABAQUS® and PYTHON programming language has been developed. A contact without friction is placed on the plane of the crack to take into account the phenomenon of c...
