A review of the use of the asymptotic framework for quantification of fretting fatigue

Abstract

We review the representation of fretting fatigue crack nucleation sites by simple asymptotic forms and show that the multipliers on these fields produce very satisfactory quantifiers of the tendency of any contact (but particularly incomplete ones) to nucleate a crack. A procedure is suggested to adopt simplified contact geometries, easily tested under carefully controlled conditions in a laboratory, to assess the likelihood of the avoidance of all failure or to estimate the time needed for crack initiation. The results found are true material properties which may then easily be used to solve a wide range of practical problems.
