The axisymmetrical free vibrations of elastic circular three-layer metal-polymeric plate on en elastic foundation are explored. Reaction of foundation was described on the base of Winkler’s model. For the kinematics description asymmetrical on the thickness of package accepted hypothesises broken normal. Filler is light. Analytical deciding a problem are received and their numeric analysis are conducted.
