(author)This research presents a coupled thermomechanical modelling procedure for the wheel-rail contact problem and computes the flash-temperature and stress-strain responses when thermal effects are present. A three-dimensional elasto-plastic finite element model was built considering the wheel-track interaction. When the wheel is running on rail,...journal article 2018

Wu, J. (author), Petrov, R.H. (author), Naeimi, M. (author), Li, Z. (author), Dollevoet, R.P.B.J. (author), Sietsma, J. (author)White etching layer (WEL) is a frequently observed microstructural phenomenon in rail surface, formed during dynamic wheel/rail contact. It is considered as one of the main initiators for rolling contact fatigue cracks. There are several hypotheses for the formation mechanism of WEL. However, due to the complicated wheel/rail contact...journal article 2016
