PREDICTION OF FATIGUE CRACK GROWTH IN RAIL STEELS
Measures to prevent derailments due to fatigue failures of rails require adequate knowledge of the rate of propagation of fatigue cracks under service loading. The report presents a computational model for the prediction of crack growth in rails. The model was derived on the basis of experiments of crack growth under service simulation loading. The applications of the model are discussed. Material data on fatigue crack growth in rail steels are required for the execution of the predictive model. Such data were generated during the present program, but reported elsewhere.
