- •
The FE wheel/rail model takes into account cyclic elastic-plastic deformation.
- •
Effect of plastic deformation on crack driving force is investigated.
- •
Dependence of crack driving force on wheel position is analysed in detail.
- •
The specific role of the plastic deformation near the crack tip is discussed.
- •
The configurational force concept is numerically verified.
