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 ...

Optimal shot peening residual stress profile for fatigue
(Elsevier B.V., 2021)
Shot peening (SP) is frequently used as a palliative measure against metal fatigue in many engineering components. The performance of this surface treatment depends on different factors including the material, shape and ...

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 ...

Mejora de la resistencia a fatiga por fretting con el tratamiento de shot peening
(Grupo español de fractura, 2017)
En aplicaciones de la industria se aplica el tratamiento superficial de shot peening para introducir tensiones residuales de compresión y así aumentar la vida a fatiga. Este tratamiento es tanto más efectivo cuanto mayor ...

Fatigue behavior of notched and unnotched AM Scalmalloy specimens subjected to different surface treatments
(Elsevier, 2024-04)
In the present work, the fatigue resistance values of Scalmalloy specimens obtained by selective laser melting (SLM) additive manufacturing (AM) are experimentally studied. The fatigue levels of specimens with and without ...

Study of the shot peening surface roughness in fretting
(Elsevier, 2024-05)
Fretting fatigue manifests in mechanical systems exposed to contact forces that vary over time, resulting in premature cracks that can lead to component failure. Shot peening treatment is one of the palliatives to mitigate ...
