Investigation of wear and ratcheting response of head-hardened Australian rail steel under conditions of rolling contact fatigue

Athukorala, Asitha Chandimal (2016) Investigation of wear and ratcheting response of head-hardened Australian rail steel under conditions of rolling contact fatigue. PhD by Publication, Queensland University of Technology.

Abstract

The work in this thesis comprehensively investigates the effects of non-uniform material behaviour exhibited by head-hardened Australian rail steel on ratcheting, wear and rolling-contact fatigue. As a result, this research develops novel approaches to characterising rolling-contact fatigue utilising wear debris and surface replication. Furthermore, calibration of material parameters was conducted to obtain a unified material model to elucidate the non-uniform mechanical behaviour of rail steel. All these methods draw attention to the need to refine track maintenance and re-railing practices related to Australian rail steel.

Impact and interest:

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
