| Abstract: | Based on the Wilkins two-dimensional algorithm, a method is developed for the numerical study of the geometrically and physically
nonlinear axially symmetrical dynamic stress-strain state of multilayer thick-walled cylindrical elastoplastic shells with
different spiral reinforcement structures. A numerical study of the specific features in the nonlinear dynamic behavior of
single-and two-layer cylinders is carried out for different reinforcement configurations and loading amplitudes.
