An ad-hoc fretting wear tribotester design for thin steel wires
Llavori, Inigo; Zabala, Alaitz; Tato, Wilson; Aginagalde, Andrea; Gómez Rodríguez, Xabier (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 ... -
An all-in-one numerical methodology for fretting wear and fatigue life assessment
Llavori, Inigo; Tato, Wilson; Gómez Rodríguez, Xabier (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 ... -
A coupled 3D wear and fatigue numerical procedure: Application to fretting problems in ultra-high strength steel wires
Llavori, Inigo; Zabala, Alaitz; Mendiguren, Joseba; Gómez Rodríguez, Xabier (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 ... -
Definición de una metodología optimizada para la simulación del desgaste en materiales
Cruzado, Aitor; Zabala, Alaitz; Gómez Rodríguez, Xabier (Consejo Superior de Investigaciones Científicas (CSIC), 2010)The wear simulation with finite element method (FEM) presents great advantages for the improvement of components, because of the reduction in the cost in comparison to the experimental procedure (test time, materials, ... -
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
Llavori, Inigo; Zabala, Alaitz; Tato, Wilson; Gómez Rodríguez, Xabier (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 ... -
Finite element modelling and experimental validation of fretting wear in thin steel wires
Cruzado, Aitor (Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2012)Fretting wear is one of the main degradation mechanism produced in steel wire ropes. This phenomenon leads to produce wear scars between the contacting thin steel wires reducing considerably the fatigue life of these ... -
Fretting : review on the numerical simulation and modelling of wear, fatigue and fracture
Llavori, Inigo; Esnaola, Jon Ander; Zabala, Alaitz; Larrañaga, Miren; Gómez Rodríguez, Xabier (InTech Europe, 2018) -
Simulación numérica y validación experimental de fenómenos de desgaste y fatiga por fretting en aceros trefilados de reducido diámetro
Llavori, Inigo (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 ... -
The use of areal surface topography characterisation in relation to fatigue performance
Zabala, Alaitz; Llavori, Inigo; Tato, Wilson; Aginagalde, Andrea; Gómez Rodríguez, Xabier (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 ...
