Rotation of rigid and elastic cylindrical shells elastically coupled with a platform

The critical states in simple and compound rotation of thin cylindrical shells elastically coupled with a platform are modeled theoretically. The technique developed has been implemented in a software system intended to analyze the mechanical phenomena associated with the critical states and to establish general conditions for such phenomena to occur. The results obtained may be used to model the dynamic behavior of turbine rotors in aircraft and ship engines __________ Translated from Prikladnaya Mekhanika, Vol. 42, No. 7, pp. 107–115, July 2006.
