Introduction of a fretting-fatigue mapping concept: Development of a dual crack nucleation - crack propagation approach to formalize fretting-fatigue damage
Fretting-fatigue induced by combined localized cyclic contact motion and external bulk fatigue loadings may result in premature and dramatic
failure of the contacting components. Depending on fretting and fatigue
loading conditions, crack nucleation and possibly crack propagation
can be activated. This paper proposes a procedure for estimating
these two damage thresholds. The crack nucleation boundary is formalized
by applying the Crossland high cycle fatigue criterion taking into
account the stress gradient and the ensuing #size##effect#. The prediction
of the crack propagation condition is formalized using a short crack
arrest description. Applied to a AISI 1034 steel, this methodology
allows the development of an original material response fretting-fatigue
map, where the different material responses related to crack nucleation,
crack arrest and catastrophic failure are established and formalized
