A 2.5D spectral approach to represent acoustic and elastic waveguides interaction on thin slab structures
(Elsevier, 2017)
In this paper, we propose a spectral element method (SEM) to study guided waves in coupled problems involving thin-walled structures and fluid-acoustic cavities. The numerical method is based on the subdomain decomposition ...

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). ...

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 ...

Low weight additive manufacturing FBG accelerometer: design, characterization and testing
(Elsevier, 2018-03)
Structural Health Monitoring is considered the process of damage detection and structural characterization by any type of on-board sensors. Fibre Bragg Gratings (FBG) are increasing their popularity due to their many ...

Continuous wavelet analysis of mode shapes differences for damage detection
(Elsevier, 2013)
This paper presents a new damage detection methodology for beams. It applies wavelet analysis to locate the damage from changes in the mode shapes (geometric based analysis). The proposed methodology requires the mode ...

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 ...

Soil structure interaction effects on the resonant response of railway bridges under high-speed traffic
(Taylor & Francis, 2015)
In the present contribution, the dynamic behaviour of beams traversed by moving loads including soil–structure interaction (SSI) is investigated. The main application of the study is to analyse the effects of SSI on the ...
