The dynamic behavior of reinforced shells of revolution in an elastic medium is modeled. Pasternak’s model is used. A problem
of vibration of discretely reinforced shells of revolution is formulated and a numerical algorithm is developed to solve it.
Results from an analysis of the dynamic behavior of a reinforced spherical shell on an elastic foundation are presented as
an example

An approach to the solution of problems on the deformation of locally loaded orthotropic shells of revolution is proposed.
Some analytical transformations are carried out to reduce the initial resolving system of partial differential equations to
the form where the constant terms representing the surface loads are continuous functions of the circumferential coordinate.
This allows us to accelerate the convergence of the trigonometric series that represent the desired solution. One-dimensional
boundary-value problems are solved by a stable numerical method. Examples of solving problems on the stress state of a cylindrical
shell are presented.
The scientific results of the present work were obtained during implementation of Project No. 14 of the Ukrainian Scientific
and Technological Center.

The paper outlines a numerical procedure for solving physically and geometrically nonlinear problems of statics for thin shells
based on three mesh-based methods: finite-difference, variational difference, and finite-element methods. The methodological,
algorithmic, and analytical aspects of implementing the Kirchhoff–Love hypotheses are analyzed. The algorithmic approach employs
Lagrangian multipliers. The advantages and disadvantages of these methods are evaluated

An approach to the solution of problems of the statics of shallow orthotropic shells is proposed. It is based on reducing
a two-dimensional boundary value problem to a one-dimensional one using the spline-collocation method and solution of the
problem by the stable numerical method of discrete orthogonalization. Solutions are presented for problems on the stress state
of orthotropic shells of double curvature for several values of the elastic constants of the material.
