Deformation E22 for 5 cases

This article presents the problem of non-stationary oscillations of reinforced ellipsoidal shells, taking into account the discrete location of the ribs. Problem bases on a geometrically nonlinear variant of the Tymoshenko theory for shells and rods. A numerical method for solving problems of this class has been developed and substantiated. This article focuses on the location of the reinforcing ribs. Based on the developed numerical method the deformed state of discretely supported ellipsoidal shells for internal, external, and internal-external placement of ribs is investigated. Boundary conditions for rigidly clamped edges of the shell were studied.
