CECM: a continuous empirical cubature method with application to the dimensional hyperreduction of parameterized finite element models
(Elsevier, 2024-01)
Article
Open AccessWe propose a method for finding optimal quadrature/cubature rules with positive weights for parameterized functions in 1D, 2D or 3D spatial domains. The method takes as starting point the values of the functions at the ... -
Efficient crack length measurement using A* shortest path methodology for a phase-field fracture framework
(2023-06-05)
Article
Open AccessAccurately measuring a crack length is a crucial aspect of experimental fracture tests. In this work, we present an innovative application of the A* (A-star) shortest path methodology to track different shapes of cracks from ... -
Improved intensity measures considering soil inelastic properties via multi-regression analysis
(Frontiers Media SA, 2023-08)
Article
Open AccessAt certain depths, the elastic properties of the ground are not affected by seismic waves. However, as they reach the surface, the soil density decreases and so does its elastic limit. This means that the expected ground ... -
Correlation between seismic intensity measures and engineering demand parameters of reinforced concrete frame buildings through nonlinear time history analysis
(Elsevier, 2023-11)
Article
Open AccessIn this paper, the correlation between different seismic intensity measures (IM) and engineering demand parameters (EDP) of reinforced concrete (RC) buildings was evaluated by means of nonlinear dynamic analyses (NLDA). ... -
Experimental and numerical study on the detection of fatigue failure in hydraulic turbines
(Springer, 2023-10-06)
Article
Open AccessDetecting fatigue cracks in hydraulic turbine runners is costly, as it requires to stop the unit, empty it of water and access the runner for inspection. Thus, an alternative way based on monitoring the changes of the ... -
Empirical Interscale Finite Element Method (EIFEM) for modeling heterogeneous structures via localized hyperreduction
(Elsevier, 2024-01)
Article
Open AccessThis work proposes a special type of Finite Element (FE) technology – the Empirical Interscale FE method – for modeling heterogeneous structures in the small strain regime, for both dynamic and static analyses. The method ... -
Structural analysis of rack upright frames under a pure compression load by means of a nonlinear Generalized Beam Theory analysis
(2023-09)
Article
Restricted access - publisher's policyRack uprights are commonly mono-symmetric open thin-walled members with regular perforations along their length. These perforations are used to enable the connection with Rack upright frames of conventional pallet racking ... -
Cross-sectional optimization of perforated pallet rack columns against distortional and global buckling
(2023-11)
Article
Restricted access - confidentiality agreementThis paper presents a cross-sectional optimization procedure to increase the load carrying capacity of a perforated rack column under a compression load. The optimization method is based on a Genetic Algorithm (GA) combined ... -
Fatigue damage analysis of a Kaplan turbine model operating at off-design and transient conditions
(2023-09-07)
Article
Open AccessThe current renewable energy market forces hydraulic turbines to operate for longer periods of time at off-design and transient conditions. Their life expectancy is then decreased due to the wear provoked by flow instabilities ... -
Impact of printing orientation on inter and intra-layer bonds in 3D printed thermoplastic elastomers: a study using acoustic emission and tensile tests
(Elsevier, 2023-09-22)
Article
Open AccessThe use of the Material Extrusion technique with Thermoplastic Elastomers is currently growing because of the large number of benefits of this family of materials. They are processable materials with high flexibility, which ... -
EBSD-data analysis of an additive manufactured maraging 300 steel submitted to different tempering and aging treatments
(2023-06)
Article
Restricted access - publisher's policyMaraging is a high alloy steel sensitive to the precipitation of intermetallics from a supersaturated solid solution during aging heat treatments. The precipitation phenomenon is well described in the literature, which ... -
Perceived distress in assisted gait with a four-wheeled rollator under stress induction conditions
(Taylor & Francis Group, 2023-07-13)
Article
Open AccessIn assisted ambulation, the user’s psychological comfort has a significant impact not only on acceptability of mobility aids but also on overall gait performance. Specifically, in the case of rollators, negative states ...
