Nonlinear modes of motion of thin circular cylindrical shells (English)
0 references
Free flexural vibrations of a simply supported shell are studied within the framework of the nonlinear theory of flexible shallow shells. It is assumed that large-amplitude flexural vibrations are coupled with radial vibrations of the shell. Modal equations are derived by the Bubnov - Galerkin method. Periodic solutions are obtained by the Krylov - Bogolyubov method. The skeleton curve of the soft type obtained using a nonlinear finite-dimensional shell model agrees with available experimental data.
