Influence of Surface Finish and Porosity on the Fatigue behaviour of A356 Aluminium Casting Alloy

Hidalgo Coca, Raquel; Esnaola Ramos, Jon Ander; Llavori Osa, Iñigo; Larrañaga Serna, Miren; Herrero Dorca, Nuria; Hurtado Hurtado, Iñaki; Kortabarria Lezeta, Aitor (EDP Sciences, 2018)

In casting parts, due to the manufacturing process, the presence of defects such as porosity, inclusions and oxide films is unavoidable. All these irregularities have a negative effect on the component ...
Multi revolution finite element model to predict machining induced residual stresses in Inconel 718

Kortabarria Lezeta, Aitor; Arrazola Arriola, Pedro José (Elsevier, 2013)

Inconel 718 is commonly used in structural critical components of aircraft engines due to its mechanical thermal properties at high temperatures, which makes it to be considered as a difficult to machine material. In these ...
A sensibility analysis to geometric and cutting conditions using the particle finite element method (PFEM)

Arrazola Arriola, Pedro José; Kortabarria Lezeta, Aitor (Elsevier, 2013)

The (PFEM) is employed to simulate orthogonal metal cutting of 42CD4 steel. The objectives of this work are mainly three: The first one is to validate PFEM strategies as an efficient tool for numerical simulation of metal ...
