Length Scale Considerations in Fretting Fatigue

Issues concerned with self-arrest of fretting fatigue cracks at small initial lengths are discussed for a range of well-defined contact geometries. The conditions under which self-arrest will occur are given, together with the maximum tolerable initial flaw size, beyond which self-arrest may not be anticipated.

Designing against fretting fatigue: Crack self-arrest

Surface roughness and crack initiation in fretting fatigue

Two problems concerning the propagation of transverse cracks through beams are studied with a crack modelled as a distribution of dislocations. The first consists of a surface breaking normal crack present in reversing bending, where it is shown that for deep cracks two cycles of loading are experienced for each cycle of applied load. The second is an initially buried normal crack, where stress intensity factors affecting propagation both towards the surface and into the beam are evaluated. The effect on the life of each of these components is then considered for a representative material.
