Numerical modelling of fretting fatigue [PDF]

, 2011
Fretting fatigue is a consequence of small oscillatory movement between two contacting parts. This type of damage may give rise to significant reduction in fatigue life of the components.

Study on high-low cycle fretting fatigue life of Inconel718 tenon structure

Hangkong gongcheng jinzhan
The turbine blades of aero-engines are subjected to cyclic high-low cycle loads in actual service environments，which is a typical high-low cycle micro motion fatigue condition. The frequent occurrence of fatigue fracture in turbine blades due to fretting

Evaluation Of Fretting Wear On The Femoral Stem Surface [PDF]

, 2009
Fretting wear on polished femoral stems has been well documented in clinical reports, but in vitro simulation to replicate this wear has seldom been attempted and only limited success has been achieved.

Design analysis of ductile failure in dovetail connections [PDF]

, 2008
The static plastic collapse of ductile dovetail structures is investigated by three analysis methods: slip-line field (SLF) theory based on a sheet drawing model, finite element limit analysis, and linear elastic finite element analysis with adapted ...

Crack failure behaviors of Ti–6Al–4V dovetail joints subjected to fretting fatigue and effect of laser shock dimple-textured surface coated with diamond-like carbon film

Journal of Materials Research and Technology
Fretting damage can lead to a reduction in fatigue strength by more than half, due to the increased stress on the fretting surface, which accelerates crack initiation and propagation.

Mechanophores for Mechano‐Imaging in Polymeric Materials

Helvetica Chimica Acta, Volume 109, Issue 6, June 2026.
Mechanophore‐based mechanochromic systems convert mechanical forces in polymers into optical signals, enabling direct imaging of stress localization and molecular damage. This perspective highlights recent advances in mechanophore design and their use to probe local mechanics across diverse polymer matrices, and concludes by outlining opportunities for

Simulation of Fretting Fatigue in Conformal and Concentrated Contacts

Tribology Online, 2011
Fretting fatigue is a possible failure mode of rolling bearings, as well as for other machine elements with contacts. For a rotating bearing it normally can occur in the interfaces between outer ring/housing, and inner ring/shaft.

On the estimation of finite lifetime under fretting fatigue loading [PDF]

, 2018
The aim of this paper is to formulate and validate an alternative design approach suitable for predicting finite lifetime of mechanical assemblies subjected to constant amplitude (CA) fretting fatigue loading.

Study on Multi‐Step Deformation Mechanisms and Synergistic Regulation of Strength and Ductility in Ti‐2Al‐2.5Zr Alloy Tubes for Nuclear Power Applications

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT To overcome the strength–ductility trade‐off in fabricated Ti‐2Al‐2.5Zr alloy tubes, we systematically investigated the microstructural evolution and mechanical behavior throughout thermomechanical processing, including hot working (forging and extrusion) and cold multi‐pass rolling.
