Determination of elastic characteristics of layered media for acoustic profiling problems

The paper defines four elastic characteristics of a layered medium based on known solutions of dispersion equations for longitudinal and transverse waves, with parallel and perpendicular propagation relative to the layers of the layered structure. The layered medium was considered as an analogue of a crystal of hexagonal symmetry, where the fifth elastic characteristic is determined when a transverse wave propagates at an angle to the surface of the layered structure. The full set of elastic parameters of the layered structure can be used to calculate classification features when solving the problem of classifying types of bottom soil during acoustic profiling.
