The role of contact mechanics in multiscale modelling of train-track interaction phenomena

Paper in proceeding, 2018

The paper examines possibilities for holistic modelling of the running gear/track interaction and related phenomena-in particular material deterioration phenomena. The required resolution, accuracy and challenges in understanding, describing and (in particular) modelling these phenomena are addressed. Special focus is put on contact modelling, which commonly sets the limit for the level of accuracy that can be achieved in subsequent analyses.
