Abstract: A variational principle is used to study the oscillations of a reinforced thin cylindrical shell with a filler under axial compression with allowance for friction on their contact surface. The dependences of frequencies of natural oscillations on the number of waves in a circumferential direction are constructed.

Keywords: shell, oscillation, elastic modulus, deformation, total energy, friction coefficient.
