O stateczności dynamicznej powłoki stożkowej przy pulsujących siłach podłużnych i poprzecznych z uwzględnieniem nieliniowego tłumienia materiałowego

The paper deals with the dynamical stability analysis of a thin-walled truncated conical shell, free supported at the edges. The shell is loaded by the longitudinal forces N(t), and the external uniformly distributed hydrostatic pressure p(t) changing periodically with time. Supporting on the Davidenkov's hypothesis the influence of the material damping to the parametric resonance was taken into account. The main resonance areas were derivated, and the influence of the basic physical and geometrical parameters to the dynamical instability was investigated.
