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 ...

An accurate treatment of non-homogeneous boundary conditions for development of the BEM
(Elsevier, 2020-07)
This paper proposes an enhancement of the treatment of non-homogeneous boundary conditions to improve the boundary element method (BEM) formulation. The standard formulation is modified by introducing the boundary conditions ...

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 ...
