Free Vibrations of an Elastic Two-Layer Plate

The theory of free vibrations of a two-layer elastic plate is developed on the basis of a flat formulation of the problem on the basis of exact solutions of the equations of the linear theory of elasticity in transformations. Equations of vibrations of symmetric vibrations of an infinite in plan two-layer plate are obtained. An algorithm is proposed that allows one to uniquely determine the VAT of an arbitrary layer of a plate.
