    A Review of the Rolling Contact Fatigue of Rail Wheels Under Various Stresses
    (Springer, 2022-12-20) Tawfik, M. Nur; Padzi, M. Md; Abdullah, S.; Harmanto, Dani; Firdaws, M. N.; Hapaz, H.
    This research paper reviews the recent works on the rolling contact fatigue of rail wheels. The topic covered includes the mathematics equations of rail-wheel contact stress and fatigue, RCF defects in the rail, the development of cracks, and the strategies used to reduce the rate of RCF defects. Therefore, the main understandings of RCF as they currently stand are crucial for the improvement and mitigation on rail fatigue failures in the future. This research paper has not been published yet and has not been discussed yet by the Malaysia Railway Network.

    Experiment and Smith, Watson and Topper model parameter to correlate fatigue life of rail steel
    (Research Square Platform LLC, 2023-12-28) Tawfik, M. Nur; Padzi, M. M .; Abdullah, S.; Harmanto, Dani
    This paper examines the correlation of fatigue life of R260 steel with using experiment and Smith,Watson and Topper model parameter. In order to correlation the fatigue life, three specimens have been used in testing for tensile strength in gaining properties of mechanical and eighteen specimens used for fatigue testing with using Servo-Pulser fatigue machine less 100 kN. In the meantime, the strain gauges were attaching to all specimens to measure the strain amplitude with one to one specimen during in run fatigue testing. All specimens were prepared in accordance standard E466-15 dimension and setting with R=-1 as fully reversed at room temperature with using constant loading amplitude and frequency of 10Hz. The main findings show that both experiment and SWT model parameter the best fit and a good agreement for correlation fatigue life.
