Numerical procedure for predicting the rolling contact fatigue crack initiation

Rolling Contact Fatigue Life of Rail for Different Slip Conditions

“…Much of research on fatigue life estimation from RCF crack can be found in the published literature (Ekberg and Sotkovszki, 2001;Haidari and Tehranib, 2015;Makino et al, 2012;Reis and Freitas, 2014;Sciammarella et al, 2016;Sraml et al, 2003). Ringsberg and his coworkers (Ringsberg and Josefson, 2001;J.…”

Rail surface crack initiation analysis using multi-scale coupling approach

“…For example, in predicting fatigue life of rails and wheels (Desimone et al, 2006, Ekberg et al, 2002, simple engineering formulas are commonly utilized together with Multibody system(MBS) analysis. However, due to the assumption of rigid components and elastic material behaviour in MBS simulation, a continuum approach, Finite element method(FEM) cooperating with advanced fatigue life models (Liu et al, 2006, Ringsberg et al, 2000, Sraml et al, 2003 is often employed to do crack initiation/propagation analysis because of its striking versatility. In FEM analysis, material behaviour can be described by sophisticated elasto-plastic models.…”

Micro-mechanism of rolling contact fatigue in Hadfield steel crossing

“…For understanding and predicting the fatigued problems of mechanical parts, such as wheel-rail, wheel-crossing, gears and rolling bearings, lots of theoretical and numerical studies have been conducted recently [10][11][12][13][14][15][16]. In particular, Sraml et al established a computational numerical model for contact fatigue damage analysis of mechanical elements, which is used to understand the fundamental contact problems of a cylinder and flat surface [14].…”
