Analysis of oscillations of a spherical cavity located in elastic media

Oscillations of an empty spherical cavity located in an elastic medium are considered in this paper. The cavity volume remains constant while its center is periodically displaced by the oscillations. The frequency dependence of the amplitude of oscillations caused by the resulting force acting on the cavity walls and occurring due to the wave motion in the medium is analyzed. The possibility of the reso-nance maximum appearance in the frequency dependence of the oscillation response is investigated. All possible elastic parameters corresponding to the materials with the properties including both solid and water-like media and to two types of the boundary conditions such as a slipping sphere and a frozen sphere are employed in the analysis. A comparison with the oscillation characteristics of a pulsating spherical cavity is also presented.
