Influence of crack micro-roughness on the plasticity-induced fatigue propagation in high strength steel [PDF]
Fracture and Structural Integrity, 2017 This article deals with the locally multiaxial fatigue behaviour of high strength steel. To this end, the influence of the cracking path deflections (at the micro level) on the plasticity-induced fatigue crack growth is analyzed.
