Fracture mechanical analysis of railway wheels with rolling defects

  • Reusable solid wheels manufactured of the old steel BV1 (nearly equivalent to the solid or monobloc wheel steel R1 according to the new nomenclature) show in some cases rolling defects on the surface of the wheel disc. The fatigue behaviour of such defects is analysed by means of the linear-elastic fracture mechanics and Monte Carlo simulation and assessed to be able to derive the allowable defect size for the non-destructive testing.
