Surface roughness is modelled in a way that would increase the far-field stress. Compressive residual stresses translated as closure stresses which tend to reduce the application of the far-field stress by introducing this closure stress on the crack flanks and thus the propagation of the crack is expected to be somewhat reduced compared to the unpeened condition. 2008 artículo científico 1665-7381 https://www.redalyc.org/articulo.oa?id=76811732003 en http://www.redalyc.org/revista.oa?id=768 Ingeniería Mecánica.
