Development of a model for predicting worn profile of rail under the mixed slip conditions

open access: yesNihon Kikai Gakkai ronbunshu, 2020
Rail wear does not develop in a short term, but it is closely related to crack initiation. Furthermore, there is a possibility that the worn profile of rail influences the curving performance or the running stability.
