PREDICTION OF FATIGUE-CRACK GROWTH IN RAILROAD RAILS

Methods for timely detection of fatigue cracks in rails in order to prevent failures are reviewed. Fatigue-crack-growth properties of rail steels were generated. Crack-growth experiments were performed using train-by-train service simulation stress histories based on measured load spectra. A rationale was developed to predict crack-growth in rails under service loading.
