Equivalent Conditions for Elasto-Acoustics
Résumé
We present Equivalent Conditions (ECs) for the diffraction problem of elasto-acoustic waves in a solid medium surrounded by a thin region of fluid medium. This problem is well suited for the notion of ECs : since the thickness of the layer is small with respect to the wavelength, the effect of the fluid on the solid is as a first approximation local. These conditions approximate the acoustic waves which propagate in the fluid region. We present numerical results to illustrate the accuracy of ECs.
