(2021-03-04)
Esta tesis presenta el desarrollo de dos métodos de fatiga multiaxial basados en un modelo físico formulado a partir de consideraciones energéticas, siendo su ámbito de aplicación la fatiga de altos ciclos (HCF).El documento ...
Composite Mould Design with Multiphysics FEM Computations Guidance
(MDPI, 2023-02-17)
Composite moulds constitute an attractive alternative to classical metallic moulds when used for components fabricated by processes such as Resin Transfer Moulding (RTM). However, there are many factors that have to be ...
Latest Developments to Manufacture Metal Matrix Composites and Functionally Graded Materials through AM: A State-of-the-Art Review
(MDPI, 2023-02-20)
Multi-material structure fabrication has the potential to address some critical challenges in today’s industrial paradigm. While conventional manufacturing processes cannot deliver multi-material structures in a single ...
On Constraints and Parasitic Motions of a Tripod Parallel Continuum Manipulator
(MDPI, 2023-01-06)
A parallel continuum manipulator (PCM) is a mechanism of closed-loop morphology with flexible elements such that their deformation contributes to its mobility. Flexible hexapods are six-degrees-of-freedom (DoF) fully ...
Novel Assessment Methodology for Laser Metal Deposition of New Metallic Alloys
(MDPI, 2023-01-09)
Metal additive manufacturing technologies are gaining great interest. However, the existing metallic alloys are generally formulated for conventional manufacturing processes. Thus, it is necessary to adapt their chemical ...
Impact of In-Soil Ageing Effect on PLA Printed Parts Tensile Properties
(MDPI, 2023-02-09)
Material extrusion (MEX), more commonly known as fused deposition modelling (FDM/FFF), is one of the most widely used techniques in polymeric Additive Manufacturing (AM). This technology is increasingly present in fields ...
On the effects of cutting-edge angle on high-feed turning of Inconel 718© superalloy
(Springer, 2023-04)
Machining processes on heat-resistant superalloys—i.e., turbine cases, rings, or shafts—are challenging tasks. The high-added value of such parts makes cycle times be longer than expected. Recently, high-feed turning ...
Pedagogical Approaches for Sustainable Development in Building in Higher Education
(MDPI, 2021-09-13)
Education for sustainable development (ESD) is one of the great challenges that university faculties have to face. Therefore, a multidisciplinary team from the faculty of Engineering of Gipuzkoa (EIG) at the University of ...
An alternative experimental methodology to determine the diagonal cracking resistance of steel-reinforced concrete beams
(Elsevier, 2021-10-01)
[EN]An alternative experimental method for predicting the diagonal shear cracking resistance of steel-reinforced concrete beams is developed in this paper. Conventional extensometric strain-gauge rosettes are placed on the ...
Effective Position Control for a Three-Phase Motor
(MDPI, 2020-02-01)
This document presents an efficient proportional derivative (PD) position controller for three-phase motor drives. The regulator has been designed in frequency domain, employing the direct–quadrature (<i>d</i>&ndas ...
