Hardness in the range 59-66 HRC has shown to be positively correlated with rolling contact fatigue
life; greater hardness is associated with reduced wear on the surface.

 established models to design an optimal wheel profile by minimizing the difference between the target and the actual RRD function, and three approaches for choosing a target RRD function were suggested; they also used the same method to design a wheel profile by considering w/r rolling contact fatigue
(RCF) and wear; the paper shows that the RRD of wheel set on the straight line should be as low as possible in order to ensure the lateral running stability of the wheel set .
The change in material properties through the depth of the wheel rim (hardness, proeutectoid ferrite fraction, and lamellar spacing) would tend to increase the likelihood of rolling contact fatigue
crack initiation on wheels toward the end of their life.
"We have mentioned rolling contact fatigue
in the 10-year plan as a contingency should we need to ask for more funding to cover this.
These defects had their origins in gauge corner cracks, a form of rolling contact fatigue
, which had developed on the rail surface.
The aim of this project is, through the use of process modelling and full-scale testing and modelling, to enable the effective design of a laser clad layer of premium material for application to a range of track components to reduce wear and the likelihood of rolling contact fatigue
Shevtsov (2008)  analyzed the relationship between rail profile and wear index and fatigue index, mitigate rolling contact fatigue
by shifting the contact point from rolling contact fatigue
area to the rail top, and defined the criteria for selection of wheelset rolling circle radius difference (RRD) as "no wheel-rail contact point in rolling contact fatigue
area." Appropriate RRD curves were selected in this way for optimization of rail profile.
The system, contracted to Siemens in December 2012, is capable of improving the rail resistance to both wear and rolling contact fatigue
, and was designed by Siemens Metals Technologies and Centro Sviluppo Materiali SpA (RINA-CSM).
Some recent developments are shared in these 22 papers, among them rolling contact fatigue
strength testing and material developments in aerospace bearings, testing the service life of components with defects in the rolling contact fatigue
zone, rotating beam testing of bearing steels as an effective complement to a rolling contact fatigue
test, improvement in the efficiency of ultrasonic tests for evaluating macroscopic inclusions, material response bearing testing under vibration loading, and the influence of fiber flow on rolling contact fatigue
The professor, originally from Athens and based in both the Netherlands and the UK, is best known in the engineering world for his development of a theory for 'rolling contact fatigue
', which was considered worldwide as a supreme scientific achievement when it was published in 1984.
