- Post Hatfield rolling contact fatigue: the effect of residual stress on contact stress driven crack growth in rail: part 3: further data
- Kapoor, A.; Fletcher, D. I.
- This report continues from previous reports (1, 2, 3) detailing the development of crack growth models for investigating the effect of residual stress and continuously welded rail stress on running surface initiated cracks in railway rail. This report concentrates on the prediction of crack branching direction. The use of two different residual stress distributions highlights the sensitivity of crack growth rate and direction to the residual stress distribution. Predictions are made of the branching direction for initially straight cracks at 30 degrees, 45 degrees and 60 degrees below a rail surface traversed by a driving wheel.
