Multiresonant Layered Acoustic Metamaterial (MLAM) solution for broadband low-frequency noise attenuation through double-peak sound transmission loss response
(Elsevier, 2021-08)
Article
Accés obertThe problem of noise control and attenuation is of interest in a broad range of applications, especially in the low-frequency range, below 1000 Hz. Acoustic metamaterials allow us to tackle this problem with solutions that ... -
A 2.5D coupled FEM-BEM-MFS methodology for longitudinally invariant soil-structure interaction problems
(Elsevier, 2021-04)
Article
Accés obertThis paper is concerned with a new prediction methodology for longitudinally invariant soil-structure interaction problems in elastodynamics. The method uses the finite-element method to model the structure, the boundary-element ... -
An experimental exploration of the properties of random frequency response functions
(2021-01)
Article
Accés obertThe vibro-acoustic analysis of complex structures over a broadband frequency range is an extremely challenging problem that may often require the use of a hybrid deterministic-statistical approach. Due to manufacturing ... -
Numerical validation of a hybrid approach for the assessment of vibrations and re-radiated noise in buildings due to railway traffic
(2020-12-25)
Article
Accés obertIn this paper, a hybrid experimental/numerical methodology for the assessment of railway induced ground-borne noise and vibration in buildings based on experimental measurement in the ground surface is proposed and validated. ... -
Prediction of mechanical properties of human rib cortical bone using fractal dimension
(Gordon and Breach Science Publishers, 2020-10-26)
Article
Accés obertA large number of post mortem human subjects was used to investigate the relation between the micro-structure of rib cortical bone and the mechanical properties using Fractal Dimension. Uniaxial tensile tests were performed ... -
Investigation on electromagnetic vibration energy harvesting in water distribution control valves
(2020)
Article
Accés obertControl stations of a water distribution system monitor several variables such as the pressure, the flow, and the quality of water. For these monitoring tasks, wireless sensor networks with ultra-low power consumption ... -
Nonlinear impact of traction rod on the dynamics of a high-speed rail vehicle carbody
(Springer, 2020-12)
Article
Accés obertThis paper focuses on the bogie-carbody nonlinear dynamic interaction of a Shinkansen high-speed rail vehicle. The Euler-Bernoulli beam model is used to simulate vertical elastic vibrations of the carbody. As a novelty, ... -
Traffic noise assessment based on mobile measurements
(2021-01)
Article
Accés obertContinuous noise monitoring based on mobile systems could provide a quick feedback to assess the effect of policies implemented by authorities to mitigate noise pollution. The present research verifies that mobile measurements ... -
A methodology based on 2.5D FEM-BEM for the evaluation of the vibration energy flow radiated by underground railway infrastructures
(Elsevier, 2020-07-01)
Article
Accés obertIn this paper, a comprehensive numerical approach for modelling track/tunnel/soil systems in the context of ground-borne railway-induced vibration problems considering a full-space model of the soil is proposed. All the ... -
An efficient experimental methodology for the assessment of the dynamic behaviour of resilient elements
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-06-27)
Article
Accés obertThe assessment of the dynamic behaviour of resilient elements can be performed using the indirect method as described in the standard ISO 10846-3. This paper presents a methodology for control the error on the estimation ... -
A numerical and scaled experimental study on ride comfort enhancement of a high-speed rail vehicle through optimizing traction rod stiffness
(SAGE PUBLICATIONS INC, 2021)
Article
