XFEM crack growth virtual monitoring in self-sensing CNT reinforced polymer nanocomposite plates using ANSYS
(Elsevier, 2022-03)
This paper presents an eXtended Finite Element Method (XFEM)-based numerical scheme to compute electrical resistivity changes caused by the presence of cracks and the crack growth. Using the commercial finite element package ...

Fully three-dimensional analysis of high-speed traintracksoil-structure dynamic interaction
(Elsevier, 2010)
In this paper, a general and fully three dimensional multi-body-finite element-boundary element model, formulated in the time domain to predict vibrations due to train passage at the vehicle, the track and the free field, ...

Computational Multiscale Solvers for Continuum Approaches
(MDPI, 2019-02-26)
Computational multiscale analyses are currently ubiquitous in science and technology. Different problems of interest-e.g., mechanical, fluid, thermal, or electromagnetic-involving a domain with two or more clearly distinguished ...

Multiscale Characterisation of Cortical Bone Tissue
(MDPI, 2019-12)
Multiscale analysis has become an attractive technique to predict the behaviour of materials whose microstructure strongly changes spatially or among samples, with that microstructure controlling the local constitutive ...

Motion-Based Design of Passive Damping Systems to Reduce Wind-Induced Vibrations of Stay Cables under Uncertainty Conditions
(MDPI, 2020-03)
Stay cables exhibit both great slenderness and low damping, which make them sensitive to resonant phenomena induced by the dynamic character of external actions. Furthermore, for these same reasons, their modal properties ...

Análisis mediante elementos de contorno de problemas axisimétricos con cierre de grietas
(Grupo Español de Fractura, 1999)
En el presente artículo se presenta una herramienta numérica de cálculo basada en el método de los elementos de contorno (MEC) para la solución del problema elástico con presencia de contacto entre sólidos en condiciones ...

Aplicación del método de los elementos de contorno a placas con condiciones de contorno arbitrarias
(Asociación Española de Ingeniería Mecánica, 1984-12)
Se analiza el problema de flexión de placas delgadas mediante un planteamiento en ecuaciones integrales basado en la descomposición de la ecuación biarmónica del modelo de Kirchhoff, en dos ecuaciones armónicas. El ...

Prediction of in-plane stiffness properties of Non-Crimp Fabric laminates by means of 3D Finite Element analysis
(Elsevier, 2008)
Non-crimp fabric (NCF) composites are constituted by differently oriented layers of ideally unidirectional fibre tows. However, a slight waviness always appears in the tows. The applicability of the General Laminate ...

Closed-form methodology for the bending of symmetric composite plates with cutouts and non-uniform lay-up
(Elsevier, 2021-09)
The present work is focused on the development of a Lekhnitskii-based closed-form methodology for the analysis of composite plates with elliptical cutouts and non-uniform lay-up, under bending loads. Due to an innovative ...

Análisis paso a paso no-holonómico de estructuras planas sometidas a cargas repartidas
(Universitat Politècnica de Catalunya, 1986)
Se presenta en este trabajo, en primer lugar, una técnica sistemática para la generación automática de las ecuaciones de equilibrio que relacionan los momentos flectores en los extremos de las barras de una estructura; ...
