International audienceThis work concerns finite elements modeling of vibroacoustic internal problems with dissipative interfaces. The main purpose is to establish the link between absorbing material models by wall acoustic impedance and by poroelastic model based on the Biot theory. The proposed approach consists in determining the acoustic impedance parameters starting from intrinsic characteristics of the porous medium. This impedance is then introduced into the vibroacoustic finite elements formulation to take into account the dissipative aspect of the fluidstructure.Ce travail porte sur la modélisation éléments finis de problèmes de vibroacoustique interne avec interfaces dissipatives. L’objectif est de faire le lien entre une modélisat...
