“…Although translationally-invariant models may be used for studying low-frequency ground-borne vibration due to railway traffic, they are not sufficient for studying the dynamic track response at higher frequencies for track structures exhibiting periodicity. In this case, the previously discussed Floquet transform may be applied [30,32,220]. Note that the full non-linear train-track-tunnel interaction has been proposed in [221], using the aforementioned compliance formulation in the time domain.…”

This paper reviews issues and developments in the field of structure-environment interaction problems, in which the environment is an elastic body, possibly unbounded. It covers in particular the fields of soil-structure interaction, ground-borne noise and vibration emitted by transportation systems and wave diffraction by obstacles in an elastic medium. The general setting for a linear bounded structure coupled to an unbounded linear environment through a bounded interface is first recalled, and the domain decomposition technique classically used for its description is put up. Extensions for the cases of non-linear structure and uncertain environment are then discussed. Finally, the ongoing research in the fields of unbounded interface, moving interface, and multiple interfaces are reviewed and summarized.

“…These modes can however be computed much more efficiently using Fourier theory as detailed in (Clouteau et al, 2005) for the periodic structures and (Sternchüss, A. and Balmes, E. and Jean, P. and Lombard, JP., 2008) for cyclic symmetry.…”

Revue des composites et des matériaux avancés, Lavoisier, 2009, 19 (3) ABSTRACT. Active control has often been considered for low frequency noise control of aircraft or helicopter trim panels. The present study proposes a methodology for numerical homogeneization of honeycombs and shell models of piezoelectric patches. These models are validated experimentally. The considered honeycomb is shown to be significantly viscoelastic and local bending effects are shown to limit achievable active control performance. Finally modeling strategies for the integration of the model in a numerical design process are discussed.RÉSUMÉ. Le contrôle actif à souvent été considéré pour la maitrise du bruit basse fréquence des panneaux d'habillage des avions et hélicoptères. Dans le cas de panneaux en nid d'abeille, les résultats n'ont pas toujours été à la hauteur des attentes. L'étude présentée introduit un modèle détaillé de panneau en nid d'abeille équipé de patchs piézoélectriques et valide ce modèle expé-rimentalement. L'utilisation de modes périodiques permet une analyse détaillée de l'influence des constituants dans le comportement vibratoire du nid d'abeille. Les effets viscoélastiques présents pour le Nomex sont par ailleurs mis en évidence. Du point de vue électrique, on montre que la flexibilité résiduelle induit une cloque, flexion très localisée des peaux. La performance atteignable par le contrôle actif est donc limitée. Finalement, des stratégies pour l'intégration du modèle proposé dans un processus de conception sont discutées.

“…First, a model for the dynamical interaction of the track, the tunnel and the soil is used to compute the wave field radiated into the soil due to forces applied on the rails in the tunnel. The dynamic track-tunnel-soil interaction model is based on the periodic coupled Finite Element-Boundary Element (FE-BE) formulation proposed by Clouteau et al [61]. Subsequently, a model for the dynamic interaction of the soil and the building is used to compute the structural vibration induced by this incident wave field.…”

Computer Methods in Applied Mechanics and Engineering, Elsevier, 2008Elsevier, , 197, pp.589-608. <10.1016Elsevier, /j.cma.2007 Inversion of probabilistic structural models using measured transfer functions ⋆ AbstractThis paper addresses the inversion of probabilistic models for the dynamical behaviour of structures using experimental data sets of measured frequency-domain transfer functions. The inversion is formulated as the minimization, with respect to the unknown parameters to be identified, of an objective function that measures a distance between the data and the model. Two such distances are proposed, based on either the loglikelihood function, or the relative entropy. As a comprehensive example, a probabilistic model for the dynamical behaviour of a slender beam is inverted using simulated data. The methodology is then applied to a civil and environmental engineering case history involving the identification of a probabilistic model for ground-borne vibrations from real experimental data.
