Simulation of distortion due to machining of thin-walled components
(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 ...
Multi revolution finite element model to predict machining induced residual stresses in Inconel 718
(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)
(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 ...
Numerical study of the pressure drop phenomena in wound woven wire matrix of a Stirling regenerator
(Elsevier, 2013)
Friction pressure drop correlation equations are derived from a numerical study by characterizing the pressure drop phenomena through porous medium of both types namely stacked and wound woven wire matrices of a Stirling ...
Fully pipelined implementation of tree-search algorithms for vector precoding
(Hindawi, 2013)
The nonlinear vector precoding (VP) technique has been proven to achieve close-to-capacity performance in multiuser multipleinput multiple-output (MIMO) downlink channels. The performance benefit with respect to its linear ...
