Characterization of crack nucleation in TA6V under fretting-fatigue loading using the potential drop technique [PDF]

open access: yes, 2010
Crack initiation in a Ti-6Al-4V alloy was investigated experimentally in fretting fatigue conditions. A cylinder-plane geometry was used for the contact, and partial slip conditions were considered.

Fretting fatigue fracture behavior of Ti6Al4V dovetail joint specimens at 500°C treated with nanosecond stacked femtosecond laser impact strengthening [PDF]

open access: bronzeFatigue & Fracture of Engineering Materials & Structures
The high‐temperature fretting fatigue damage characteristics of dovetail specimens strengthened by nanosecond laser (NL) and nanosecond combined femtosecond laser (F‐NL) were investigated.

Development of a fretting-fatigue mapping concept: The effect of material properties and surface treatments [PDF]

open access: yes, 2009
Fretting-fatigue induced by combined localized cyclic contact motion and external bulk fatigue loadings may result in premature and dramatic failure of the contacting components.

Multiaxial High Cycle Fretting Fatigue [PDF]

open access: yesMATEC Web of Conferences, 2019
The aim of this work is to show that multiaxial fatigue can be successfully adpted to model fretting problems. For instance, the paper presents (i) the critical direction method, as an alternative to the critical plane concept, to model the crack ...

Microscopic study of 5083-H321 aluminium alloy under fretting fatigue condition [PDF]

open access: yes, 2011
Fretting occurs where there is small amplitude oscillating motion between solid surfaces in contact. With even small loads or prolonged operation, fretting may lead to crack initiation followed by fretting fatigue.

Effect of wear debris on fretting fatigue crack initiation

open access: yesFriction, 2022
Both wear and fatigue occur in fretting condition, and they interact with one another during the whole process. Fretting fatigue is commonly analysed without considering the effect of wear in partial slip regime, although wear affects the lifetime of ...

Research on Fretting Fatigue of Tungsten Carbide Coating Based on Strain Energy Density Methods [PDF]

open access: yesArchives of Metallurgy and Materials, 2023
The numerical solutions of stress and strain components on the critical plane of tungsten carbide coating were solved based on the critical plane method in three-dimensional coordinate system, and accordingly three strain energy density parameters (Smith-

Equivalent configurations for notch and fretting fatigue [PDF]

open access: yesFracture and Structural Integrity, 2015
Under the typical partial slip conditions under which fretting fatigue takes place, the amount of superficial damage is small. Therefore, the substantial reduction in fatigue life caused by fretting, when compared to plain fatigue, may well be more ...

Fretting Fatigue Test and Simulation Analysis of Steam Generator Heat Transfer Tube

open access: yesMetals, 2022
In a steam generator, the heat transfer tubes are supported by the contact with support plates and anti-vibration bars. The two-phase flow flows over the tubes and causes a vibration when operating.

Estimation Method of Relative Slip in Fretting Fatigue Contact by Digital Image Correlation

open access: yesMetals, 2022
An experimental method that can quantify relative slip was developed using digital image correlation (DIC) in order to evaluate the sliding portion. The bridge-type test setup was designed to establish the fretting contact condition.
