3D analysis of railway induced vibrations on skew girder bridges including ballast track–bridge interaction effects
(Elsevier, 2023-03)
This work is devoted to the analysis of the vibratory response of High-Speed (HS) multi-track railway bridges composed by simply-supported spans. In particular, it aims to investigate the influence of three geometrical ...

Vibrations induced by HST passage on ballast and non-ballast tracks
(Elsevier, 2010)
The use of ballastless slab track is significantly increasing in HST line technology. This development is due to some structural and operational advantages over ballasted track. In addition, floating slab tracks can be ...

A continuum large-deformation theory for the coupled modeling of polymer–solvent system with application to PV recycling
(Elsevier, 2023-06)
Nowadays recycling of photovoltaics (PV) using the solvent method is becoming a very hot topic as massive products deployed in the last century have approached the end of their service lifetime. The key problem in the ...

Influencia del número de llaves en la resistencia a cortante de juntas secas postensadas
(2013)
La resistencia a cortante en las juntas secas es una parte importante del diseño de estructuras de dovelas postensadas. Sin embargo, la formulación de las distintas normativas no se ajusta al comportamiento de las ...

A semi-discrete line-free method of monopoles for dislocation dynamics
(Elsevier Ltd, 2021)
We develop a semi-discrete particle method for Volterra dislocation currents in which the particles, or monopoles, represent an element of line and carry a Burgers vector. The monopoles move according to mobility kinetics ...

Estudio del efecto escala en laminados [0,90n]s de material compuesto
(Sociedad Española de Integridad Estructural. Grupo Español de Fractura, 2021-07)
El efecto escala en materiales compuestos es conocido como el retraso en la aparición de daño en las láminas más débiles de un laminado (típicamente las láminas a 90 grados). Esta cuestión ha adquirido una enorme relevancia ...

University accreditations and publication of articles on education in Spain
(Routledge (Taylor & Francis), 2021)
In recent years, Spain has been far and away the leader in records of publications on education in indexed international journals. For several years, the accreditation requirements of university professorates have included ...

Fast simulation of railway bridge dynamics accounting for soil–structure interaction
(Springer, 2021-08)
A novel numerical methodology is presented to solve the dynamic response of railway bridges under the passage of running trains, considering soil–structure interaction. It is advantageous compared to alternative approaches ...

The effect of rolling stock characteristics on differential railway track settlement: An engineering-economic model
(Elsevier, 2022-11)
Railway track geometry deteriorates under repeated train loading. When linespeed is increased or new rolling-stock is introduced this can alter the future rate of change of differential settlement and track geometry. ...
