“…Among the most well-known wear models, especially in fretting fatigue applications, we can highlight for their wide use and easy applicability the local formulations of Archard's equation [7,25] or the dissipated friction energy [26,27]. Archard's equation for sliding wear can be expressed as [6]:…”

“…On the other hand, the update of contact tractions has an impact on the wear evolution process. In the literature [7,9,17] there are two approaches to the finite element analysis of contact problems with wear. For the contact problems where the amounts of generated wear are suitably small, the shape change of the contact surface due to wear is neglected.…”

“…The wear evolution [16][17][18] may have a significant impact on the analysis and numerical solution of the contact problem. The material loss in the contact area can generate a significant change in its shape and the redistribution of the contact tractions.…”

This work is concerned with the numerical procedure to solve two-dimensional wheel-rail contact problem between a rigid wheel and an elastic-plastic rail lying on a rigid foundation. The contact phenomenon includes Coulomb friction, frictional heat generation as well as the wear of the contacting surfaces. The wear depth function appears as an internal variable in the non-penetration condition updating the gap between the worn surfaces of the bodies. Moreover the dissipated energy due to friction is calculated to evaluate the loss of material and to determine the shape of the contacting surfaces during the wear evolution process. This contact problem is solved numerically using the finite element method as well as the operator splitting approach and semi-smooth Newton method. The distribution of contact surface stresses and temperatures as well as the evolution of the shape of the contact surfaces and the wear depth are reported and discussed.

Wear and rolling contact fatigue (RCF) cracks are the key defects affecting the service life of heavy‐haul railways in China. In this study, based on the influences of the loading sequence and the interaction between adjacent loads, a modified nonlinear fatigue damage accumulation model under the steady‐state wheel–rail contact was developed to predict the coexistence of wear growth and head check (HC) initiation. A twin‐roller fatigue test was designed and performed, and the testing data were compared with the predicted data to verify the established model. Compared with the linear model, the nonlinear model yielded the faster fatigue damage with an HC initiation life of 2.58 × 105 wheel cycles, which was 24.34% less than that of the linear model. In addition, the HC initiation lives obtained from the nonlinear and linear models were close to the median and upper limits observed in the field, respectively. The results of the linear and nonlinear models were respectively 41.3% and 22.5% higher than the two‐round test results. The result of the nonlinear model was closer to the two‐round test result of 2 × 105.
