Piramedov I.T., Candidate of Physical and Mathematical Sciences; Institute of Mathematics and Mechanics, Azerbaijan of NAS; Baku, the Republic of Azerbaijan

In the paper, by means of the variational principle investigate parametric vibrations of a thin, in homogeneous in thickness viscoelastic damageable cylindrical shell with viscoelastic filler, under the action of external pressure p=p0+p1sinω1t (where p0 is the mean or main load, p1 is the amplitude of change of load, ω1 is frequency of is change, in geometrically nonlinear statement.
