Abstract
The results of integrated studies of the slow relaxation of the sound speed in structurally inhomogeneous materials after vibratory action with a finite strain amplitude are presented. The results were obtained using an experimental setup created for these studies, which ensured highly accurate measurements of the linear and nonlinear acoustic characteristics of various materials. The results of an experimental study of relaxation in carbonate rock, which is a structurally inhomogeneous material with a complex system of internal relationships, are presented. The measurements made it possible to determine the dependence of the relaxation parameters on the amplitude and time of excitation, as well as the effects caused by the finite amplitude of the probing wave. The results are interpreted, and effects that have not received an exhaustive explanation are noted.
