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 ...

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 ...

Experimental results in fretting fatigue with shot and laser peened Al 7075-T651 specimens
(Grupo español de fractura, 2012)
This work focuses on determining the effect of shot and laser peening on fretting fatigue in the Al 7075-T651 alloy. These surface treatments generate a residual compressive stress field near the treated surface where ...

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 ...

Contact conditions and stresses induced during fretting fatigue
(WIT Press, 1999)
This paper analyses the contact conditions and stresses induced during fretting fatigue tests of uniaxial specimens using fretting bridges with spherical-tip contact pads. This analysis considers the displacement of the ...
