DISPERSION OF WAVES IN AN INFINITE POROELASTIC PLATE IMMERSED IN AN INVISCID ELASTIC FLUID
Краткое описание
Wave propagation in a poroelastic plate immersed in an inviscid elastic fluid is studied employing Biot’s theory in plane-strain form. Frequency equations are derived for pervious and impervious surfaces, and for a poroelastic plate in contact with an inviscid elastic fluid and poroelastic plate in vacuum, as a particular case. Phase velocity as a function of propagation constant is computed for pervious and impervious surfaces in each case, i.e., a poroelastic plate immersed in an acoustic medium, a poroelastic plate in contact with an inviscid fluid, and a poroelastic plate in vacuum without dissipation. It is observed that generally, the phase velocity of pervious and impervious surfaces is the same for water-saturated sandstone while it differs for kerosene-saturated sandstone in each of these three cases.
