The solution of the problem of bending vibrations of a composite sample, which makes it possible to determine the amplitudes of its oscillations and resonant frequencies, is obtained. A comparison is made of the experimentally determined resonance frequencies of flexural and longitudinal oscillations of a composite sample with values calculated theoretically. The maximum discrepancy does not exceed 20%, which indicates the validity of the proposed calculation methods.
