Numerical analysis of rolling contact fatigue crack initiation and fatigue life prediction of the railway crossing

Numerical analysis for fatigue life prediction on railroad RCF crack initiation

In the present paper, a numerical procedure for surface crack initiation analysis based on the critical plane approach is proposed. The complex stress/strain state of wheel and rail (W/R) contact is analysed by means of submodelling approach together with the transient contact nodal loads obtained from dynamic W/R rolling contact analysis....
