.../methodology/approach By considering the stress-free boundaries, the frequency equation is obtained in the presence of dissipation. Limiting case when the ratio between thickness and inner radius is very small is investigated numerically. In the limiting case, the asymptotic expansions of Bessel functions...

...Baljeet Singh Purpose The purpose of this paper is to compute the phase velocities and attenuation coefficients of coupled longitudinal waves in a generalized thermoporoelastic model and to observe the effect of porosity, frequency and thermal parameters on the phase velocities and attenuation...
