ON INTERACTION OF VIBRATION MODES OF THIN CIRCULAR CYLINDRICAL SHELLS WITH DIFFERENT PARAMETRES OF WAVE FORMATION
The paper considers small flexural vibrations of a thin-walled circular cylindrical shell with Navier boundary conditions. It is believed that the shell has initial deviations from the ideal circular shape. The analysis is based on the equations of motion within the theory of shallow shells. It has been established that initial imperfections may lead to an intensive interaction of flexural modes with different, but close, numbers of circumferential waves.
