The article presents the results of a study of the contact zone of a thin-walled cylindrical shell located between two parallel rigid plates. The shell under consideration was located with various gaps from the rigid plate and was subsequently subjected to internal pressure. In the course of such a study, experimental, numerical and analytical estimates of the contact zone width were obtained depending on the discharge pressure. The obtained numerical and analytical estimates are tested with experiment. To study the width of the contact zone, depending on the gap, a testing workbench was used. The problem of numerical and analytical modelling was solved by the finite element analysis in the Ansys Workbench system. The solution to transcendental equation was found numerically using the Newton-Raphson method. As a result of experimental, numerical and analytical studies, results were obtained for a plane-oval shell with gaps of 0.5 mm, 1 mm and 2 mm, depending on the applied pressure.
