Title High-Precision Analytic Solution of the Problem on Bending Vibrations of a Clamped Square Plate
Author(s) S.V. Nesterov (Ishlinsky Institute for Problems in Mechanics, Russian Academy of Sciences, pr. Vernadskogo 101, str. 1, Moscow, 119526 Russia,
Abstract An original iteration algorithm is used to construct new analytic expressions for computing approximate natural frequencies and shape modes of bending vibrations of a square homogeneous plate clamped along its contour. The errors are estimated by comparing with the results of well-known numerical high-precision computations. The results of analytic computations are also compared with experimental data obtained by the author by the resonance method. The proposed research technique and the obtained high-precision expressions for the natural shape modes can be used in the case of rectangular plates and for other types of boundary conditions.

A numerical-analytical method is used to show that the small isoperimetric theorem holds.
Keywords square plate, natural frequency, natural shape mode, modified Rayleigh method, small isoperimetric theorem
