Abstract

For the development of rail materials with improved properties regarding rolling contact fatigue and wear it is at first important to know and understand the loading conditions in railway operation. Based on the loading conditions crack initiation can be predicted. This has been done with the so-called wedge model, which takes the plastic shear deformation condition in a layer near the rail surface into account. Results for a specific railway operation scenario and test rig experiments are compared, which contributes to the understanding of the transferability of test rig results to the behaviour in the field.
