Evolution of residual stresses induced by machining in a Nickel based alloy under static loading at room temperature

Madariaga Zabala, Aitor; Arrazola Arriola, Pedro José; Esnaola Ramos, Jon Ander (Elsevier, 2014)

Tensile residual stresses are very often generated on the surface when machining nickel alloys. In order to determine their influence on the final mechanical behaviour of the component residual stress stability should be ...
Numerical Simulation of Surface Modification During Machining of Nickel-based Superalloy

Arrazola Arriola, Pedro José; Imaz Ciaran, Mikel; Rotella, Giovanna (Elsevier, 2015)

The main objective of this study is to implement a reliable FE model of the orthogonal machining of a Nickel based superalloy for the prediction of microstructural changes occurring during the process. A FE numerical model ...
Simulation of distortion due to machining of thin-walled components

Arrazola Arriola, Pedro José (Elsevier, 2013)

The distortion of components is strongly related to the residual stress state induced by manufacturing processes like heat treatment, forming or machining. Each process step affects the initial stress state of the following ...
