High-speed train-induced ground motion and interaction with structures
(Elsevier, 2007)
A general numerical model for the analysis of soil motion due to high-speed train passage and effects on nearby surface and underground structures is presented in this paper. Soil, ballast and structures are represented ...

Efecto de la zona de contacto entre fibra y matriz en las propiedades de fractura de materiales compuestos sometidos a carga transversal
(Grupo Español de Fractura, 1997)
El presente trabajo trata de dilucidar si en presencia de despegues entre fibra y matriz, se produce contacto circunferencial entre ambas fases cuando el conjunto está sometido a carga transversal a la fibra. Se utiliza ...

Fitting the fracture curve of concrete as a density function pertaining to the generalized extreme value family
(Elsevier, 2017-09)
The load-displacement (P-δ) curve, recorded during the fracture process of concrete in three-point bending tests, is supposed to depict a fracture phenomenon of statistical character that can be suitably described by a ...

Analysis of ground motion due to moving surface loads induced by high-speed trains
(Elsevier, 2007-11)
A three-dimensional time domain boundary element (BE) approach for the analysis of soil vibrations induced by high-speed moving loads is presented in this paper. An attenuation law is included in the formulation. By doing ...

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 ...

Cálculo del término no singular de tensiones en una grieta 3D mediante una integral independiente del dominio
(Grupo Español de Fractura, 2006)
El término no singular de tensiones, denominado también “T-stress”, es el término asociado al autovalor λ =1 en la serie desarrollada por Williams (1957) para el campo de tensiones lineal elástico cercano al vértice de ...

A 2.5D coupled FE-BE model for the prediction of railway induced vibrations
(Elsevier, 2010)
Ground vibrations induced by railway traffic at grade and in tunnels are often studied by means of two-and-half dimensional (2.5D) models that are based on a Fourier transform of the coordinate in the longitudinal direction ...
