Estimating the material parameters of an inhomogeneous poroelastic plate from ultrasonic measurements in water
Matti Niskanen, Aroune Duclos, Olivier Dazel +3
The estimation of poroelastic material parameters based on ultrasound measurements is considered. The acoustical characterisation of poroelastic materials based on various measurem…
Characterising poroelastic materials in the ultrasonic range - A Bayesian approach
Matti Niskanen, Olivier Dazel, Jean-Philippe Groby +2
Acoustic fields scattered by poroelastic materials contain key information about the materials' pore structure and elastic properties. Therefore, such materials are often character…
Coupling of Finite-Element and Plane Waves Discontinuous Galerkin methods for time-harmonic problems
Mathieu Gaborit, Olivier Dazel, Peter Göransson +1
A coupling approach is presented to combine a wave-based method to the standard finite element method. This coupling methodology is presented here for the Helmholtz equation but it…
Using simple shape three-dimensional inclusions to enhance porous layer absorption
Jean-Philippe Groby, Benoit Nennig, Clément Lagarrigue +3
The absorption properties of a metaporous material made of non-resonant simple shape three-dimensional inclusions (cube, cylinder, sphere, cone and torus) embedded in a rigidly bac…
Quasi-total absorption peak by use of a backed rigid frame porous layer with circular periodic inclusions embedded
Jean-Philippe Groby, Olivier Dazel, Aroune Duclos +2
The acoustic properties of a porous sheet of medium resistivity backed by a rigid plate in which are embedded a periodic set of circular inclusions is investigated. Such a structur…
Validity of the one-dimensional limp model for porous materials
Olivier Doutres, Nicolas Dauchez, Jean-Michel Génevaux +1
A straightforward criterion to determine the limp model validity for porous materials is addressed here. The limp model is an "equivalent fluid" model which gives a better descript…
