Optimization of NDT inspection intervals

  • The Starcrack software (developed by Lucchini RS and Politecnico di Milano) models the propagation of a crack in an axle under variable service loads.
  • By introducing the POD (Probability of Detection) of the NDT equipment, the software calculates the probability of failure for a given inspection interval.
  • The Starcrack software was validated trough extensive testing on full scale axle rotating bending test rig (BDA)
