Rolling Contact Fatigue/Gauge Corner Cracking 

RCFRolling Contact Fatigue is the name given to a damage mechanism that occurs in rails, rail wheels, bearings and gears. In rails, rolling contact fatigue generates GCCGauge Corner Cracking, which manifests itself as a series of surface or near-surface cracks on the rail. They tend to grow downwards at an angle of between 10° and 30° to the surface of the rail. Rolling contact fatigue differs from the typical fatigue mechanism due to several specific conditions.
