THESIS: A STUDY INTO THE OCCURRENCE OF SUBSURFACE ROLLING CONTACT FATIGUE CRACKS IN THE WHEELS OF RAILCORPÂ’S OUTER SUBURBAN CAR FLEET.

 

Place of Study: University of Wollongong.

The thesis describes a static finite element analysis and stress distribution study that was carried out on the wheels of part of the RailCorp Outer Suburban Car (OSCAR) fleet as part of a process designed to address the incidence of some rolling contact fatigue cracks that had initiated below the wheel treads. The results of the study have contributed towards a better understanding of the propagation and behaviour of these rolling contact fatigue cracks and they have assisted in the development of optimised wheel re-profiling activities.
