T1 Symmetric Oscillations of a Porous-Elastic Strip with Free Surfaces for the Case of Closed Pores JF International Journal of Fluid Mechanics Research JO FMR YR 2001 FD 2001-12-10 VO 28 IS 6 OP 12 AB Dispersion characteristics of the natural modes of a porous-elastic strip with free surfaces for the case of closed pores are studied in the context of the Biot theory. Due to the existence of the three types of waves in a porous fluid-saturated medium, the dispersion spectrum, even obtained without consideration of the dissipative effects, is considerably more complicated than the spectrum of a perfectly elastic strip. This spectrum is distinguished by existence of infinitely many pure imaginary roots at a specified frequency. In addition, there are two real branches passing through the coordinate origin in a porous-elastic strip with closed pores.
