NONLINEAR VIBRATIONS OF FLUID-FILLED CYLINDRICAL SHELLS WITH INITIAL IMPERFECTIONS

摘要

Theoretical approaches to studying the free vibrations of imperfect (with small geometrical imperfections) orthotropic cylindrical shells filled with a fluid are proposed. A geometrically nonlinear problem is solved. The emphasis is on the interaction and energy exchange between the "conjugate" flexural modes in the dynamic radial deflection. The effect of initial deflections on the interaction of the initial deflection modes is analyzed.
