A comparative study of residual stress profiles on Inconel 718 induced by dry face turning
Kortabarria, Aitor; Madariaga, Aitor; Fernandez, Eduardo; Esnaola, Jon Ander; ARRAZOLA, PEDRO JOSE (Elsevier, 2011)Residual stress profiles induced by different dry face turning conditions are compared employing X-ray diffraction method, Hole-Drilling method and Finite Element Modelling. It is well known that the surface integrity ... -
Influence of Surface Finish and Porosity on the Fatigue behaviour of A356 Aluminium Casting Alloy
Hidalgo, Raquel; Esnaola, Jon Ander; Llavori, Inigo; Larrañaga, Miren; Herrero-Dorca, Nuria; Hurtado, Iñaki; Kortabarria, 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 ... -
Influence of tool wear on residual stresses when turning Inconel 718
Madariaga, Aitor; Kortabarria, Aitor; Hormaetxe Fernández, Exabier; Garay, Ainara; ARRAZOLA, PEDRO JOSE (Elsevier, 2016)This paper analyzes the effect of tool wear on residual stresses when turning. Inconel 718 discs were machined for prolonged periods at several cutting speeds, feed-rates and depth of cut. Tests were interrupted to measure ... -
Multi revolution finite element model to predict machining induced residual stresses in Inconel 718
Kortabarria, Aitor; ARRAZOLA, PEDRO JOSE (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, PEDRO JOSE; Kortabarria, 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 ...
