Designing against fretting fatigue: Crack self-arrest
Reads0
Chats0
Abstract:
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.read more

A review of analytical aspects of fretting fatigue, with extension to damage parameters, and application to dovetail joints
TL;DR: In this paper, the authors analyzed the impact of plane fretting fatigue contact problems and derived new consequences for FF damage, showing that the surface damage parameters decrease, but the tensile stress concentration increases, suggesting that for cracks eventually initiated, the likelihood of self-arrest is higher than in the equivalent Hertzian case with same loads.

The effect of surface regular microtopography on fretting fatigue life
TL;DR: In this article, the possibility of increasing the fretting fatigue life of a tribo-pair by laser surface texturing technology is studied, and a relatively small number of long-fretting fatigue experiments under seemingly partial slip condition are described and analyzed.

A combined wear and crack nucleation–propagation methodology for fretting fatigue prediction
TL;DR: In this paper, a finite element based methodology for predicting the effects of fretting wear on crack nucleation and propagation under fretting fatigue conditions is presented, where wear under gross sliding conditions significantly retards propagation rate whereas wear under partial slip conditions is predicted to increase crack propagation rates across the slip zone.

Characterisation of fretting-induced wear debris for Ti-6Al-4 V
TL;DR: In this article, a nano-indentation technique was used to measure the mechanical characteristics of the debris layer and the alloy immediately below the layer, as produced from cylinder-on-flat fretting wear tests on Ti-6Al-4V.

Simple parameters to predict effect of surface damage on fretting fatigue
TL;DR: In this paper, two empirical parameters for the prediction of fretting were presented, the first is a simple parameter, Dfret1, 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.

Numerical solution of singular integral equations
TL;DR: In this paper, the numerical methods for the solution of two groups of singular integral equations are described, which arise from the formulation of the mixed boundary value problems in applied physics and engineering.

TL;DR: In this article, the mechanism of fretting fatigue failure is discussed from the experimental results, and the condition of non-propagating cracks is also known, which coincides with the knee point in the propagation curve.

Crack initiation criteria in fretting fatigue
David Nowell,David A. Hills +1 more
TL;DR: In this paper, a series of fretting fatigue tests on an Al/Cu alloy was performed, in which the contact size was varied while the other relevant parameters were held constant.
