WebApr 1, 1993 · Abstract. The velocities and attenuation of seismic and acoustic waves in rocks with fluids are affected by the two most important modes of fluid/solid interaction: (1) the Biot mechanism where the fluid is forced to participate in the solid's motion by viscous friction and inertial coupling, and (2) the squirt-flow mechanism where the fluid is … WebJul 23, 2008 · Plona’s recent measurements of elastic‐wave speeds in a water‐saturated porous structure of sintered glass beads are compared quantitatively to the predictions of …
