A finite-element solution of the problem on natural vibrations of a plate compliant in transverse shear is considered. A four-node rectangular finite element whose basic nodal kinematic parameters include the angles of transverse shear deformations is used. A comparative analysis of frequencies and modes of natural vibrations of composite and sandwich plates is performed for two variants of boundary conditions on their contour: the classical clamping and clamping with free transverse shear deformations.
