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…
Surface waves in granular phononic crystals
Helene Pichard, Aroune Duclos, Jean-Philippe Groby +3
The existence of surface elastic waves at a mechanically free surface of granular phononic crystals is studied. The granular phononic crystals are made of spherical particles distr…
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…
Multiple Scattering and Visco-Thermal Effects on 2D Phononic Crystal
Aroune Duclos, Denis Lafarge, Vincent Pagneux
In this paper, we are interested in the transition between regimes here either visco-thermal or multiple scattering effects dominate for the propagation of acoustic waves through a…
