A novel 2.5D spectral approach for studying thin-walled waveguides with fluid-acoustic interaction
(Elsevier, 2018-07)
This paper presents a novel formulation of two spectral elements to study guided waves in coupled problems involving thin-walled structures and fluid-acoustic enclosures. The aim of the proposed work is the development of ...

Modeling elastic wave propagation in fluid-filled boreholes drilled in nonhomogeneous media: BEM – MLPG versus BEM-FEM coupling
(Elsevier, 2017)
The efficiency of two coupling formulations, the boundary element method (BEM)-meshless local Petrov–Galerkin (MLPG) versus the BEM-finite element method (FEM), used to simulate the elastic wave propagation in fluid-filled ...

Soil-structure interaction in resonant railway bridges
(Elsevier, 2013)
This paper explores dynamic soil–bridge interaction in high speed railway lines. The analysis was conducted using a general and fully three-dimensional multi-body finite element–boundary element model formulated in the ...

Respuesta dinámica de edificaciones producida por campos de ondas incidentes considerando la interacción suelo-estructura
(Centro Internacional de Métodos Numéricos en Ingeniería (CIMNE) de la Universitat Politécnica de Catalunya (UPC) ; Elsevier, 2014)
En este artículo se presentan dos metodologías basadas en las formulaciones de los métodos de los elementos de contorno y de los elementos finitos para estudiar el efecto de la interacción suelo-estructura en el comportamiento ...

Ballast shear effects on the dynamic response of railway bridges
(Elsevier, 2022-12-01)
Single-track railway bridges are susceptible of experiencing high levels of vertical acceleration on the deck that may be dangerously accentuated at resonance. This is especially critical for short-to-medium span simply ...

Damage detection in beams from modal and wavelet analysis using a stationary roving mass and noise estimation
(Wiley, 2018-04)
This paper uses the Continuous Wavelet Transform Analysis on mode shapes for damage identification. The wavelet analysis is applied to the difference in the mode shapes between a healthy and a damaged state. The paper also ...

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 ...

Dynamic characterisation of wind turbine towers account for a monopile foundation and different soil conditions
(Taylor & Francis (Routledge), 2017)
The response of wind turbines is induced by dynamic loads such as wind, transient and cyclic loads, and also extreme loads such as earthquakes. Thus, the structural design requires an accurate evaluation of the modal ...
