Increased patronage of railways in the UK in the past 20 years has put demands on rolling stock to operate at peak availability with reduced time available for maintenance. One possible tool to enable this is the use of real time fault detection and diagnosis on board railway vehicles to detect faulty components and provide information about the current running condition of the system. This pap...

A Failure Assessment Diagram (FAD), developed for rolling contact, was specifically formulated railway wheel steels. The FAD allows combining a multiaxial fatigue criterion with the linear elastic fracture mechanics concept; in particular, it used to assess failure wet related pressurization of fluid entrapped surface cracks. approach applied results previous bi-disc tests carried out on three ...
