Predicción de la Vida a Fatiga por Fretting en la Aleación de Aluminio 7075-T6 con Contacto Esférico
(Grupo español de fractura, 2013)
Este artículo analiza el comportamiento de piezas sometidas a laser y shot peening ante ensayos de fatiga por fretting. En estos ensayos el material era aluminio Al 7075-T651 y los elementos de contacto tenían forma ...

Experimental study on the fretting fatigue of Inconel 718 superalloy
(Elsevier, 2023)
Fretting fatigue is a surface damage phenomenon appearing in mechanical assemblies subjected to time-varying contact forces. This type of failure is a very frequent problem in many engineering components, with special relevance ...

3D contact effects in fretting fatigue tests
(Elsevier, 2022-04)
Fretting fatigue is a material damage phenomenon produced in mechanical contacts. This phenomenon mainly produces surface cracking, and depending on the fretting regime, surface wear. In the bibliography many different ...

Effect of rolling on fretting fatigue assessment of cylindrical contact in partial slip regime
(Elsevier, 2023)
The present research work deals with the fatigue assessment of an Al 7075-T651 subjected to fretting fatigue testing characterised by cylindrical contact. A small rolling of the pads is experimentally observed and, ...

Fretting-Fatigue Analysis of Shot-Peened Al 7075-T651 Test Specimens
(MDPI AG, 2019-05)
Shot peening is a mechanical treatment that induces several changes in the material: surface roughness, increased hardness close to the surface, and, the most important, compressive residual stresses. This paper analyzes ...

Influence of the rolling of contact pads on crack initiation in fretting fatigue tests
(Elsevier, 2022-10)
This work performs a detailed analysis of the cracks obtained in fretting fatigue tests with cylindrical contact in the presence of a small oscillatory rolling of the contact pad. To do so, fretting fatigue tests have been ...

Effect of the model’s geometry in fretting fatigue life prediction
(Gruppo Italiano Frattura (IGF), 2014)
This paper analyses the influence that the type of geometry used to obtain the stress/strain fields in a cylindrical contact has on fretting fatigue life predictions. In addition, this work considers the effect that ...

A fretting fatigue model based on self-steered cracks
(Elsevier B.V., 2022-02)
In this article a new fretting fatigue life prediction model is presented. The model can be classified as a variable crack initiation length: the crack initiation and crack propagation phases are calculated as a function ...

Prediction of initiation and total life in fretting fatigue considering kinked cracks
(Elsevier, 2022-06)
This work proposes a methodology to compute fretting fatigue crack initiation and total life by iterative models calibrated with fatigue stress–strain-life curves. One of the main novelty of such models is the assumption ...
