Abstract

In this article, on the basis of the Lagrange variation equation, integral-differential equations of natural vibrations of a viscoelastic ribbed truncated conical shell are obtained. The general research methodology is based on the variational principles of mechanics and variational methods. Geometrically nonlinear mathematical models of deformation of ribbed conical shells are obtained taking into account such factors as discrete introduction of ribs.
