abstracts | The paper deals with the problem of time harmonic vibrations of a rigid block on a water-saturated sand subsoil. The main interest is focused on the phenomenon of mechanical energy dissipation in the two-phase medium due to the flow of the viscid fluid through the pores of the solid. The behaviour of the saturated poro-elastic medium is studied on the basis of Biot's dynamic theory of consolidation. The problem is solved in a discrete way by using the finite element method. In order to confine the analysis to a finite domain, artificial boundaries are introduced, on which approximate absorbing conditions for Biot's medium are applied. Numerical results, obtained for three types of the block vibrations, illustrate the distribution of energy dissipation density in the subsoil. The influence of the frequency of oscillations and the sand permeability on the energy dissipation is investigated. Some results related to the problem of wave energy transmission are also presented. |
