Effect of External or Internal Static Pressure on the Natural Frequencies of Unstiffened, Cross Stiffened, and Sandwich Cylindrical Shells

摘要

A general formula is given for the natural frequency of a pressurized shell which is loaded with static load on its cylindrical surface as well as along its edge. It is found that the natural frequency of the pressurized shell can be written in terms of the natural frequency of the unpressureized shell. The connection between natural frequencies and buckling load is discussed. (Author)
