Influence of crack micro-roughness on the plasticity-induced fatigue propagation in high strength steel by J. Toribio, J.C. Matos, B. González

“…With regard to this, a modelling by means of the finite element method was performed for a given stress intensity factor in the Paris regime, considering the existence of micro-roughness in the crack path (local micro-deflections with distinct micro-angles as a function of the microstructure of the material). The numerical results allow one to obtain the fatigue crack propagation rate and compare it with that for the same material in the absence of microroughness (with no micro-crack deflections, i.e., uniaxial fatigue behaviour).…”
