Abstract
In work the problem about vibrations of viscoelastic orthotropic plates with variable rigidity is considered. The equations of vibrations concerning deflections are described by the integro-differential equations (IDE) in partial derivatives. By means of Bubnov-Galerkin method based on polynomial approximation of deflections, the problem is shown to research of system of the ordinary IDE where an independent variable is time. Decisions of IDE are determined by the numerical method based on elimination of a singularity in a kernel. On the basis of this method the algorithm of the numerical decision is described.
