The use of areal surface topography characterisation in relation to fatigue performance
(EDP Sciences, 2018)
Although the effect of surface topography on fatigue life is widely accepted, the underlying role of surface roughness from first principles is still poorly understood. Currently approaches which consider the ...
Influence of Surface Finish and Porosity on the Fatigue behaviour of A356 Aluminium Casting Alloy
(EDP Sciences, 2018)
In casting parts, due to the manufacturing process, the presence of defects such as porosity, inclusions and oxide films is unavoidable. All these irregularities have a negative effect on the component ...
Development of a Modular Fretting Wear and Fretting Fatigue Tribometer for Thin Steel Wires: Design Concept and Preliminary Analysis of the Effect of Crossing Angle on Tangential Force
(MDPI AG, 2019)
This work presents the design of a modular ad-hoc fretting fatigue and fretting wear tribotester for thin steel wires. The working principles of the diffrent modules are described, such as the displacement and contact ...
An ad-hoc fretting wear tribotester design for thin steel wires
(EDP Sciences, 2018)
Steel wire ropes experience fretting wear damage when the rope runs over a sheave promoting an oscillatory motion between the wires. Consequently, wear scars appear between the contacting wires leading to an ...
Simulación numérica y validación experimental de fenómenos de desgaste y fatiga por fretting en aceros trefilados de reducido diámetro
(Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2016)
Many mechanical components such as, bearing housings, exible couplings and spines or steel wires are simultaneously subjected to fatigue and fretting damage. Fretting phenomenon arises when two bodies are in contact subjected ...
On the Role of Contact and System Stiffness in the Measurement of Principal Variables in Fretting Wear Testing
(MDPI AG, 2020)
In this work, the role of the contact stiffness in the measurement of principal variables in fretting wear tests is assessed. Several fretting wear tribometers found in the literature, including one developed by the authors, ...
A coupled 3D wear and fatigue numerical procedure: Application to fretting problems in ultra-high strength steel wires
(Elsevier Ltd., 2021)
This work presents a coupled 3D wear and fatigue numerical procedure for fretting problems in ultra-high strength steel wires that combines Archard’s wear equation with the Smith–Watson–Topper parameter to predict crack ...
Surface integrity of additive manufacturing parts: a comparison between optical topography measuring techniques
(Elsevier B.V., 2020)
Additive Manufacturing (AM) presents significant industry-specific advantages allowing the creation of complex geometries and internal features that cannot be produced using conventional manufacturing processes. However, ...
An all-in-one numerical methodology for fretting wear and fatigue life assessment
(Gruppo Italiano Frattura, 2016)
Many mechanical components such as, bearing housings, flexible couplings and spines or orthopedic devices are simultaneously subjected to a fretting wear and fatigue damage. For this reason, the combined study on a single ...
