- Аннотация: In this paper we present the results of theoretical and experimental studies of longitudinal acoustic wave propagation of small and finite amplitude in the model granular unconsolidated media (GUM) and in a fluid – saturated granular unconsolidated media (FGUM) under an uniaxial pressure P. For modeling of the GUM we used steel balls of various diameters. For modeling of the FGUM space between balls in GUM was filled with various liquids: ethanol, glycerin and hydrocarbon. A structural phase transition induced by the static (external pressure) and dynamic (amplitude of the acoustic wave) influences was examined.
