Roughness- and plasticity-induced fatigue crack closure under single overloads: analytical modelling

Singh, Konjengbam Darunkumar, Khor, Kern Hauw and Sinclair, Ian (2006) Roughness- and plasticity-induced fatigue crack closure under single overloads: analytical modelling Acta Materialia, 54, (17), pp. 4405-4414. (doi:10.1016/j.actamat.2006.04.016).

Record type: Article


A simple micromechanical model for the competitive influences of roughness-induced crack closure (RICC) and plasticity-induced crack closure (PICC) on fatigue during single peak overloads has been developed following the approach of Kamp et al. [Kamp N, Parry MR, Singh KD, Sinclair I. Acta Mater 2004;52:343]. This is seen to be functionally comparable to the finite element results of the accompanying paper [Singh KD, Khor KH, Sinclair I. Acta Mater 2006;54:4393], and consistent with a range of experimental data. Competitive influences of PICC and RICC effects during overload transients are particularly identified here.
