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, ...

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 ...

Induced vibrations due to high-speed trains: Córdoba-Málaga high speed line
(Sociedad Española de Acústica, 2007)
Numerical models to obtain ground vibrations induced by the passage of HST, based on finite element method and boundary element method, have been developed in the last years. A few models have been validated, comparing the ...

Unique real‐variable expressions of displacement and traction fundamental solutions covering all transversely isotropic elastic materials for 3D BEM
(Wiley, 2008)
A general, efficient and robust boundary element method (BEM) formulation for the numerical solution of 9 three-dimensional linear elastic problems in transversely isotropic solids is developed in the present work. The ...

Estados singulares de tensión en esquinas multimateriales
(Grupo Español de Fractura, 2007)
La unión entre materiales de distinta naturaleza genera puntos críticos en la estructura donde aparecen cambios bruscos en la geometría y propiedades de los materiales (esquinas multimateriales). La teoría de la Elasticidad ...
