A fracture mechanics approach is conducted on two important problems on the strength of wheelset. One is the brittle type rim fracture and the another is the fretting fatigue crack propagation at the fitted part of axle assemblies. In both cases, the critical conditions for crack growth and final failure could be dealt with by experimental analysis based on a linear fracture mechanics. The means are found by which the effect of material properties and service condition on the ciritical strength can be evaluated. (Wassmann)
