Acoustic wave propagation in double porosity media.
The homogenization technique for periodic separated scales media, is applied to realistic double porosity materials with motionless skeleton, and it is shown that the macroscopic descriptions depend on the contrast of static permeability between pores and micropores and on frequency.
Assessment of the Urbanization Effect on Seismic Response

The interest of in situ measurements (presented in Part I paper) for a seismic assessment of existing buildings is analysed in this paper. It is shown that the experimental modal characteristics…
Deformable porous media with double porosity III: Acoustics
- J. Auriault, C. Boutin
- Physics
- 1 February 1994
We investigate the acoustics of saturated porous media with a double porosity constituted by pores and fractures. This work is the direct extension of earlier papers by Auriault and Boutin, where the…

- 1 July 2005
AbstractWe investigate the validity of Darcy’s law when the separation of scales is poor. We use the method of multi-scale asymptotic expansions which gives the macroscopic behaviour from the pore…
