- •
The purpose of this paper is to analyze the influence of wear on RCF crack growth.
- •
The maximum stress caused by wheel/rail contact was obtained.
- •
The stress history is used to calculate SIFs and fatigue life of rail.
- •
Failure of rail the influence of wear was analyzed to identify the cause.
- •
Results showed that the effect of wear on the fatigue life is remarkable.
