A unified algorithm based on the Ostrogradsky-Hamilton principle was elaborated for the numerical calculation of free vibration frequencies, critical values of statical loads, and domains of dynamical instability of parametric vibrations of non-homogeneous rotary shells widely used in the aerospace technology.
Keywords: dynamical instability, non-homogeneous rotary shells, Ostrogradsky-Hamilton principle
