S.P. Tymoshenko of the National Academy of Sciences of Ukraine popup.description2  Free vibrations of two classes of elastic objects are considered: conjugate systems of shells of rotation and non-circular cylindrical shells. The free vibrations of heterogeneous shells conjugated in one system, which differ in their shape, structure in thickness, physical and mechanical properties of the material, and other features, have been studied. The solution of the problem of free vibrations of orthotropic non-circular cylindrical shells with variable thickness under different boundary conditions is obtained. The influence of the shell shape, the law of thickness change, and the properties of the material on the distribution of the free frequency spectrum has also been studied. The study of free vibrations of elastic isotropic cylindrical shells of elliptical cross section using the spline collocation method is carried out.
