The influence of cutting edge microgeometry on the broaching of Inconel 718 slots
(Elsevier, 2023-12)
In aero-engine production, the dovetails (firtrees) of turbine discs are manufactured by broaching. Introducing innovative micro-geometry modifications to broaching tools can significantly influence cutting force, energy ...
Early detection of tool wear in electromechanical broaching machines by monitoring main stroke servomotors
(Elsevier, 2023-12)
This paper aims to provide researchers and engineers with evidence that sensorless machine variable monitoring can achieve tool wear monitoring in broaching in real production environments, reducing production errors, ...
42CrMo4 steel flow behavior characterization for high temperature closed dies hot forging in automotive components applications
(Elsevier, 2023-11)
The application of new forming processes as the high temperature hot forging in closed dies in an industrial environment still requires further investigation due to the lack of flow stress data at these temperatures. To ...
An Investigation of the Processing-Microstructure-Property Trinomial in the Production of High-Wear-Resistant Coatings by Multi-Material L-DED
(2023-09-29)
This PhD thesis aims to investigate aspects related to the process-microstructure-property trinomial in multi-material Additive Manufacturing (AM) when applied to the production of high-wear-resistant coatings. In the ...
A Cleaner Milling Process Replacing Emulsion Coolant by Cryogenics CO2
(Springer Nature, 2024-01)
In manufacturing sector, looking for a balance between environmental and technical efficiency taking into account productivity is mandatory. Some sectors, such as the biomedical manufacturing sector, also needs to consider ...
Positional influence of center of masticatory forces on occlusal contact forces using a digital occlusal analyzer
(Elsevier, 2023-06)
Statement of problem. Digital occlusal analyzers allow the recording of dental contact forces.
Some authors assume a unique location for the center of contact forces at the position of
maximum intercuspation, while others ...

El objetivo principal de la presente tesis doctoral es analizar la fractura interlaminar en modo I de laminados compuestos. Se ha realizado un análisis del ensayo DCB y de los métodos de reducción de datos.En este trabajo ...
Computational Modelling of Rectangular Sub-Boundary Layer Vortex Generators
(MDPI, 2018-01-19)
Vortex generators (VGs) are increasingly used in the wind turbine manufacture industry as flow control devices to improve rotor blade aerodynamic performance. Nevertheless, VGs may produce excess residual drag in some ...
Thermal Performance Assessment of Walls Made of Three Types of Sustainable Concrete Blocks by Means of FEM and Validated through an Extensive Measurement Campaign
(MDPI, 2021-01-04)
The thermal behavior of three different walls, made with and without by-products, is assessed by means of the Finite Element Method, aiming to evaluate its performance in terms of the sustainable construction of the blocks. ...
Wheel-rail interaction and conformal contact analysis
(2023-10-20)
Se estudia el contacto conforme rueda-carril, 3D y con fricción, mediante simulaciones por ordenador con modelos numéricos, incluyendo una versión de la teoría exacta de contacto de Kalker extendida para contacto conforme ...
