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 ...

Scoping assessment of free-field vibrations due to railway traffic
(Elsevier, 2018-11)
The number of railway lines both operational and under construction is growing rapidly, leading to an increase in the number of buildings adversely affected by ground-borne vibration (e.g. shaking and indoor noise). ...

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 ...

Railway slab vs ballasted track: A comparison of track geometry degradation
(Elsevier, 2023-05-16)
Concrete slab railway tracks typically have higher initial capital costs yet lower operational costs in comparison to ballasted tracks. One reason for the elevated operational costs on ballasted lines is the need for more ...

Energy harvesting analysis in railway bridges: An approach based on modal decomposition
(Elsevier, 2021-04-10)
In this paper the authors investigate the energy harvesting in railway bridges and analyse the performance under different operational conditions. An approximation based on modal superposition is proposed for the computation ...

3D non-linear time domain FEM-BEM approach to soil-structure interaction problems
(Elsevier, 2013)
Dynamic soil-structure interaction is concerned with the study of structures supported on flexible soils and subjected to dynamic actions. Methods combining the finite element method (FEM) and the boundary element method ...

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 ...

On the dynamic characterisation of railway bridges through experimental testing
(Elsevier, 2021-01-01)
This work is devoted to the experimental evaluation of the dynamic response of railway bridges with common typologies in short-to-medium span lengths. An extensive experimental campaign is performed in several railway ...
