A multiscale material model for metallic powder compaction during hot isostatic pressing
(Elsevier, 2023)The prediction of the distortions during Near-Net-Shape Hot Isostatic Pressing (NNS-HIP) is an intrinsic multiscale problem where the local interactions among particles determine the macroscopic distortions taking place ... -
Thermal Mass Effect on the Solution Cooling Rate and on HIPped Astroloy Component Properties
(MDPI, 2022)Astroloy is a Ni-based superalloy with high-volume fraction of γ′, which gives high temperature properties but reduces its forgeability. Therefore, powder metallurgy manufacturing processes such as Near Net Shape HIPping ... -
Study of Astroloy powder compaction at high temperature under hydrostatic load using finite elements
(Elsevier, 2021)The results of existing constitutive models describing the behaviour of metal powder during compaction processes are very different. This reveals the high sensitivity of the mechanical behaviour of porous materials to the ... -
Study of powder densification under hydrostatic loads at high temperatures using finite element method
(Elsevier, 2020)Many different constitutive models that describe the behaviour of metal powder during hot isostatic processes are found in literature. A quantitative comparison of these material laws shows a huge discrepancy among the ... -
Optimization of the semi-hexagonal geometry of a composite crush structure by finite element analysis
(Elsevier, 2016)In the present paper a numerical model for predicting the crushing behaviour of semi-hexagonal E-glass/polyester composite structures has been developed. Qualitative and quantitative analysis have shown that the results ... -
Effectivity of fluoride treatment on hydrogen and corrosion product generation in temporal implants for different magnesium alloys
(Sage Journals, 2013)The increasing interest on magnesium alloys relies on their biocompatibility, bioabsorbility and especially on their mechanical properties. Due to these characteristics, magnesium alloys are becoming a promising solution ... -
Processing of magnesium porous structures by infiltration casting for biomedical applications
(Wiley, 2014)Magnesium and its alloys are currently considered to be a promising metallic biomaterial. The interest in magnesium alloys arises from their biocompatibility, bioabsorbility and especially from their mechanical properties, ... -
Identification of the Constitutive and Friction Models Parameters via a Multi-Objective Surrogate-Assisted Algorithm for the Modeling of Machining - Application to Arbitrary Lagrangian Eulerian Orthogonal Cutting of Ti6Al4V
(ASME, 2024)The evolution of high-performance computing facilitates the simulation of manufacturing processes. The prediction accuracy of a numerical model of the cutting process is closely associated with the selection of constitutive ... -
Transdisciplinary humanities for social transformation: The Global Digital Humanities degree at Mondragon University AS Fabrik
(Berghahn Journals, 2024-03-01)The new degree in the Global Digital Humanities has been launched by the Faculty of Humanities and Education at Mondragon University on its new urban campus of Bilbao AS Fabrik. In a time of increas- ing urbanisation, ... -
Integral Design and Manufacturing Methodology of a Reduced-Scale Servo Press
(IEEE, 2021)In a context where industrial production boosts both the society and the economy of a country, improvements in industrial processes are key factors for efficient and reliable development of goods and products. New industrial ... -
Correcting distortions of thin-walled machined parts by machine hammer peening
(Elsevier, 2023)Thin-walled aerostructural components frequently get distorted after the machining process. Reworking to correct distortions or eventually rejecting parts significantly increases the cost. This paper proposes a new approach ... -
Non-destructive experimental technique to determine ball contact load in rolling machine elements
(Elsevier, 2024)Rolling machine elements, such as ball bearings, ball screws, or guiding systems are commonly used in diverse industrial applications. These components typically assume uniform load distribution among the balls or rely on ... -
Optimización de parámetros de CNC de acuerdo a criterios de productividad usando un modelo de máquina basado en redes neuronales
(Dyna Publishing, 2020)Every machine-tool user wants to maximize the productivity of their machines looking for balance between speed, precision and lifetime of mechanical components. Nevertheless, because CNCs have wide-ranging use, their correct ... -
Development of a novel method to characterize mean surface peak curvature as a signature of tribological performance of dental implant surfaces
(IOP Publishing, 2020)The integrity of dental implant surfaces might be compromised during surgical insertion. Wear and topographical modifications can occur during implant insertion, which can potentially have clinical implications. Accordingly, ... -
Links between circular economy and climate change mitigation in the built environment
(Elsevier, 2020)The construction sector represents one of the most significant sources of waste generation in the European Union (EU), with nearly one billion tonnes of construction and demolition waste annually. This sector also contributes ... -
An analytical model of through-thickness photopolymerisation of composites: Ultraviolet light transmission and curing kinetics
(Elsevier, 2020)In this paper, a kinetic model able to predict the evolution of the through-thickness degree of cure of ultraviolet (UV) cured composites has been developed and validated. The kinetic model, which is based on the autocatalytic ... -
Impact of long-term resource variations on wave energy Farms: The Icelandic case
(Elsevier, 2020)Four decades (between 1979 and 2018) of the wave energy resource around Iceland are analysed in the present paper via the ERA5 reanalysis, the newest reanalysis of the European Centre for Medium-Range Weather Forecasts. ... -

(Dyna, 2020)La industria 4.0 y una vida laboral en continua transmutación, plantean preguntas acerca de cuáles serán las competencias que requerirán las personas para la correcta apropiación tecnológica y la mejora del desempeño. Este ... -
Novel email spam detection method using sentiment analysis and personality recognition
(Oxford Academic, 2020)Unsolicited email campaigns remain as one of the biggest threats affecting millions of users per day. During the past years several techniques to detect unsolicited emails have been developed. This work provides means to ... -
HRM systems and employee affective commitment: the role of employee gender
(Emerald, 2020)Purpose Despite decades of studies on high-involvement human resource management (HRM) systems, questions remain of whether high-involvement HRM systems can increase the commitment of women. This study aims to contribute ...
