Characterization of poroelastic materials with a bayesian approach

Abstract : A characterization method of poroelastic intrinsic parameters is used and compared with other direct methods. This inverse characterization method enables to get all the parameters with a simple measurement in a standing wave tube. It is based on a bayesian approach that enables to get probabilistic data such as the maximum aposteriori value and confidence intervals on each parameter. In this approach, it is necessary to define prior information on the parameters depending on the studied material. This last point is very important to regularize the inverse problem of identification. In a first step, the direct problem formulation is presented. Then, the inverse characterization is developed and applied to an experimental case.
