Ongoing Research

The lifetime of railway wheels and rails is often limited by wear and rolling contact fatigue (RCF). A competition exists between wear and RCF: wear can worsen the contact geometry between wheel and rail, which may accelerate crack growth, but at higher wear rates – RCF does not have the opportunity to develop further.

I am working within the project SWORD (Simulation of Wheel-On-Rail Deterioration phenomena) . The main goal of this project is to create a model for prediction of the total expected life of wheels and rails with respect to both fatigue cracking and wear.
