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 ...
