Experimental and numerical investigation of fretting fatigue behavior in bolted joints

J Juoksukangas, A Lehtovaara, A Mäntylä - Tribology International, 2016 - Elsevier
Bolted joints may suffer from fretting damage which can significantly decrease fatigue life. A
testing arrangement was developed to study the effect of different operating and design …

Effect of different surface asperities and surface hardness induced by shot-peening on the fretting wear behavior of Ti-6Al-4V

Fretting fatigue tests on shrink-fit specimens and investigations into the strength enhancement induced by deep rolling

L Bertini, C Santus - International Journal of Fatigue, 2015 - Elsevier
The shrink-fit connection undergoes fretting fatigue at the edge of the contact, where both
stress concentration and micro-slip take place. A fretting test set-up with a round-shaped …

Fretting-induced friction and wear in large flat-on-flat contact with quenched and tempered steel

J Hintikka, A Lehtovaara, A Mäntylä - Tribology International, 2015 - Elsevier
Fretting may cause severe surface damage and lead to unexpected fatigue failure. Our test
apparatus was designed based on reciprocating, large, annular flat-on-flat contact without …

[图书][B] Mechanics of fretting and fretting fatigue

DA Hills, HN Andresen - 2021 - Springer
Fatigue, popularly metal fatigue, is a primary cause of failure of structural engineering
components. Cracks may freely initiate, but this is rare unless the metal (alloy) is of poor …

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

DA Hills, D Dini - The Journal of Strain Analysis for …, 2016 - journals.sagepub.com
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 …

engines. It cites already published articles and theses with some backgrounds information. It …

Sharp edged contacts subject to fretting: A description of corner behaviour

RC Flicek, DA Hills, D Dini - International Journal of Fatigue, 2015 - Elsevier
In this paper, we use the singular terms in Williams' solution to quantify the behaviour at the
edge of a complete (ie sharp edged) contact. To do this, we define two alternative …
