Prykladni Problemy Mekhaniky i MatematykyРезюме: | The problem of free vibrations of thin shells amenable to transversal shear and compression is formulated. To find the natural frequencies and forms of free vibrations, a numerical approach based on the finite element method (FEM) and the subspace iteration method was used. The solutions of a number of model problems are considered, on which the efficiency of the proposed numerical scheme is demonstrated. The influence of compression on the behavior of the dynamic characteristics of the shell is investigated. Cite as: B. A. Zubal’, I. Ya. Kozii, O. V. Kostelna, H. A.
