This paper presents two empirical parameters for the prediction of fretting The first is a simple parameter D(fret1) which is shown to correlate test data against fretting fatigue life in terms of the so-called running conditions of contact displacement and normal load The second more complex parameter is shown to have the ability to capture (i) the effect of relative slip on fretting fatigue life and (ii) a well-known fretting fatigue contact size effect in a more rational framework This parameter combines a multiaxial fatigue parameter the constants for which can be obtained from plain-fatigue testing and a surface damage parameter D(fret2) which represents the surface damaging effect of fretting the tribological constants for which can be obtained from fretting wear and fretting fatigue test data A key benefit of D(fret3) is that It circumvents time-consuming incremental wear simulations (C) 2010 Elsevier Ltd All rights reserved
