Stability and vibrations of nonclosed circular cylindrical shells reinforced with discrete longitudinal ribs

The paper gives exact solutions to the stability and vibration problems for nonclosed circular cylindrical shells hinged along the longitudinal edges and reinforced with a regularly arranged discrete longitudinal ribs. These problems are also solved approximately in the cases of regularly and quasiregularly arranged ribs __________ Translated from Prikladnaya Mekhanika, Vol. 44, No. 1, pp. 20–27, January 2008.
