Abstract
Natural frequencies and modes of vibration, the rigidity of solids, are the most important parameters taken into account when designing structural elements in order to take into account dynamic loading conditions. The article presents the results of calculating the natural frequencies of the first forms of bending vibrations of composite plates with interlayer hybridity. The dependences of the deflections of the rods under the action of a distributed load over the surface on the internal structure are revealed. The calculations were obtained by numerical and approximate methods. For numerical analysis software based on the finite element method (ANSYS) was used.
