Probability of instant rail break induced by wheel-rail impact loading using field test data

The probability of an instant rail break, initiated at a single pre-existing rail foot crack due to a severe wheel impact loading, is predicted using statistical methods and a time-domain model for the simulation of dynamic vehicle-track interaction. A linear elastic fracture mechanics approach is e...
