metadata.value: Results of numerical studies of the influence of reinforcement orientation of hard layers and
  the relative thickness of the soft layer of an isotropic viscoelastic polymer on the values
  of natural frequencies and coefficients of mechanical losses are discussed. In a symmetrical
  three-layer plate, a bending-torsion interaction arises, generating mutual transformations
  of the eigenmodes of the coupled vibration modes, if at least one of its own forms in plate
  directions is characterized by an even number quarters of a wave, and another proper
  form   an odd number of quarters the waves. In an unsymmetrical asymmetric three-layer
  plate, bending-bending interaction arises, generating mutual transformations eigenmodes
  of coupled vibration modes in two mutually orthogonal planes if in the main directions
  of the plate both of their own forms characterized by either an even or an odd number
  of quarters of a wave. It was found that each mode of natural vibrations of three-layer plates corresponds to the effective relative thickness of the soft isotropic layer viscoelastic
  polymer.
