Experimental and numerical analysis of fatigue cracks emanating from internal defects in Ti6Al4V SLM
(Elsevier, 2021)
In the present work a series of fatigue tests on Ti6Al4V SLM parts are analyzed via both SEM and confocal microscopy. On the one hand, fracture surfaces are studied, and a common pattern is found, formed by a series of ...

Fatiga en implantes dentales
(Grupo español de fractura, 2013)
En este artículo se estudia el comportamiento ante la fatiga de implantes dentales de titanio comercialmente puro grado 4. Dichos implantes se ven sometidos a ciclos de carga y descarga durante la masticación, ...

Predicción de vida en componentes con gradientes de tensiones: entallas y fatiga por fretting
(Grupo español de fractura, 2009)
La fatiga en componentes con entalla y la fatiga por fretting son dos fenómenos diferentes pero tienen en común la existencia de un gradiente de tensiones. En estos casos la predicción de la vida a fatiga se suele realizar ...

Rolling effect in fretting fatigue test at the crack initiation stage
(Elsevier, 2022)
The aim of this work is to perform a detailed analysis of the cracks paths obtained in fretting fatigue tests with cylindrical contact but taking into account the presence of an unavoidable (due to the fretting device’s ...

Análisis del proceso de fatiga en entallas mediante la acumulación de daño en el frente de grieta
(Grupo español de fractura, 2009)
El proceso de fatiga se divide normalmente para su estudio en dos etapas: iniciación y propagación. La separación entre una y otra es arbitraria, dependiendo de cómo se definan. El modelo presentado en este ...

Comparison of two multiaxial fatigue models applied to dental implants
(Gruppo Italiano Frattura (IGF), 2015)
This paper presents two multiaxial fatigue life prediction models applied to a commercial dental implant. One model is called Variable Initiation Length Model and takes into account both the crack initiation and propagation ...

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 ...

Structural integrity of shot peened Ti6Al4V specimens under fretting fatigue
(Springer Science and Business Media B.V., 2022-04)
In the present paper, an experimental campaign performed on shot peened Ti6Al4V specimens under fretting fatigue, available in the literature, is simulated by using the Carpinteri et al. criterion. The experiments examined ...

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 ...

Fatigue behaviour of PBF additive manufactured TI6AL4V alloy after shot and laser peening
(Elsevier Ltd, 2022)
Additive manufacturing (AM) of metallic parts is a relatively new manufacturing procedure. Many industry sectors, such as the aerospace or automotive sectors, have started to apply this technology to produce some elements, ...
