In the current study a severe subsurface crack network in a railway wheel has been studied and compared to typical rolling contact fatigue cracks found in the wheel tread surface. Microstructural characteristics, chemical composition and microhardness within the cracks and around crack faces were examined. While the two damage types are principally different, both showed similar crack characteristics,...
Predicting the lifetime of a conveyor belt from lab-scale tests has become increasingly important, as the cost for the belt represents up to 70% of the acquisition and maintenance costs of a transport system. In practice, belt selection relies strongly on the well-established ISO 4649 abrasion test, where fixed corundum paper is utilised as the abrasive medium, resulting in 2-body abrasion. In the...
