Original Abstract

This study focuses on crack propagation rates of AISI 304 stainless-steel specimens made from selected structural components experimentally tested in three-point bending. Components of two productions loaded with constant force with selected stress ratio were submitted to cyclic loading in order to measure crack opening displacement. Experimentally obtained data were evaluated using 3D modelling in finite element modeling software intending to determine fracture mechanical parameters. The tool to describe fatigue behavior was Paris’ law, used to describe crack propagation in intermediate crack growth rate range. Paris–Erdogan equation was evaluated as a fitting of linear part of the graphical plot of crack growth rate with respect to the stress intensity range and material constants were gained from numerical description of the relation. Comparison of fatigue crack behavior in AISI 304 steel components of two productions was studied and evaluated.
