The second part of the inspection concept details the general conditions for wheelset operation that lead to application of a fracture mechanics evaluation concept for wheelset-shaft inspection intervals. This can be described as a fail safe concept. To form the basis for a fracture mechanics evaluation tests are carried out on original wheelset shafts from actual service for which the rate of crack growth has been determined. With the aid of the Pans law formula and stress spectrums that also encompass a documented vehicle operation profile, mileage limits can be derived for inspection intervals using the possibilities offered by non-destructive materials testing.
