Fatigue Crack Propagation in Rail Steels

Source

Baseline fatigue crack growth data at R = 0 and mechanical property data have been generated on 66 different rail materials which are in service on U.S. railroads. These data are evaluated, along with metallurgical variables such as chemical composition and microstructure, in an attempt to develop a correlation of mechanical and metallurgical factors affecting crack behavior in rail steels. The ultimate objective of this effort is the development of a rail failure model to enable the determination of safe inspection intervals, through prediction of fatigue crack growth in rail under service loading.
