New shear transfer system for concrete-filled steel tube (CFST) columns
(John Wiley & sons, 2022-05)
Article
Restricted access - publisher's policyConcrete-filled steel tube (CFST) columns are frequently used in construction due to their high ductility and improved loadbearing capacities. At beam-to-CFST column joints, gusset plates are welded to the outer face ... -
State-of-the-art review on adjustable pallet racks testing for seismic design
(2022-12)
Article
Open AccessThis paper presents a state-of-the-art review on seismic tests of adjustable pallet rack systems: on particular components of racks, subassemblies, full racks and stored goods. The tested particular components are the most ... -
Numerical simulation of a rapid fatigue test of high Mn-TWIP steel via a high cycle fatigue constitutive law
(2023-03)
Article
Open AccessThe generation of reliable data in the high cycle fatigue domain is crucial to support further metallurgic developments of fatigue optimized steel grades. Commonly employed for this aim, traditional standardized characterization ... -
Mixed stabilized finite element methods in linear elasticity for the velocity–stress equations in the time and the frequency domains
(2023-02)
Article
Restricted access - publisher's policyIn this work we present stabilized finite element methods for the mixed velocity–stress elasticity equations and for its irreducible velocity form. This is done both for the time and frequency domains, the latter being ... -
An enriched finite element/level-set model for two-phase electrohydrodynamic simulations
(2023-01-04)
Article
Open AccessIn this work, a numerical model for the simulation of two-phase electrohydrodynamic (EHD) problems is proposed. It is characterized by a physically consistent treatment of surface tension as well as a jump in the electric ... -
Multi-objective multi-scale optimization of composite structures, application to an aircraft overhead locker made with bio-composites
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-12-28)
Article
Open AccessThe use of composite materials has grown exponentially in transport structures due to their weight reduction advantages, added to their capability to adapt the material properties and internal micro-structure to the ... -
Improving glass-fiber epoxy composites via interlayer toughening with polyacrylonitrile/multiwalled carbon nanotubes electrospun fibers
(Wiley, 2022-11)
Article
Open AccessThe development of innovative engineered epoxy composites aiming to manufacture cost-efficient materials with reduced weight and enhanced physical properties remains as a current industrial challenge. In this work we report ... -
Métodos de Clapeyron y Cross para el análisis de vigas de inercia variable
(2022-06-13)
Article
Open AccessEn el mundo académico con frecuencia se plantea el análisis global de estructuras con vigas consideradas de inercia constante I. La múltiple bibliografía docente así lo atestigua. A pesar de ello, también se presentan casos ... -
Objectivity in quasi-brittle structural failure via adaptive formulation and mesh refinement
(2022-12)
Article
Restricted access - publisher's policyIn this work, the combined implementation of Adaptive Formulation Refinement (AFR) and Adaptive Mesh Refinement (AMR) strategies is proposed for the efficient and mesh objective evaluation of quasi-brittle fracture. A ... -
A unified non-linear energy dissipation-based plastic-damage model for cyclic loading
(2022-10)
Article
Open AccessA new energy-dissipation-based rate-independent constitutive law within the framework of elastoplasticity coupled with damage is proposed. With this methodology, the inelastic strains and the stiffness degradation exhibited ... -
Finite element approximation of wave problems with correcting terms based on training artificial neural networks with fine solutions
(2022-09)
Article
Restricted access - publisher's policyIn this paper we present a general idea to correct coarse models by introducing a correcting term designed from fine solutions that can be then applied to situations in which a fine solution is not available. We apply this ... -
Characterizing the structural behavior of FRP profiles—FRCM hybrid superficial elements: experimental and numerical studies
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-03)
Article
Open AccessComposite materials have been increasingly used to produce hybrid structures together with concrete. This system is commonly applied to bridges and roof structures. The main idea of the current research was to extend this ...
