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 ...

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 ...
