Abstract
This paper revisits a comprehensive data set generated in a prior test program using a full-scale wheel-rail test rig. The test program evaluated premium and standard grade rail steels with respect to wear and rolling contact fatigue (RCF). The current work evaluates the evolution of rail profiles throughout the test cases, taking advantage of the database of wheel and rail profiles that were collected. Contact conditions are modelled using the CONTACT library, including recent developments in the handling of conformal geometries and interfacial layers. Observations are made regarding the relative characteristics of rail profiles for each steel type, as they evolve with accumulated wheel passes, on the basis of the computed contact conditions.
期刊介绍：
Wear journal is dedicated to the advancement of basic and applied knowledge concerning the nature of wear of materials. Broadly, topics of interest range from development of fundamental understanding of the mechanisms of wear to innovative solutions to practical engineering problems. Authors of experimental studies are expected to comment on the repeatability of the data, and whenever possible, conduct multiple measurements under similar testing conditions. Further, Wear embraces the highest standards of professional ethics, and the detection of matching content, either in written or graphical form, from other publications by the current authors or by others, may result in rejection.
