The numerical analysis provided allow to identify new patterns and characteristic mechanical effects. The influence of different types of static axisymmetric loads in subcritical stages of deformation on the natural frequencies of elastic systems of shells rotation of different geometry was investigated. Features of low frequency areas of the spectrum of eigen vibrations of a complex shell system was illustrated. Product Description popup.authors Bespalova Olena I. Boreiko Nataliia P.
