Abstract:

The influence of initial uniform circumferential and axial stress on the frequency of vibrations of simply supported circular cylindrical shells has been previously investigated on the basis of shell theories which can be anticipated to yield accurate results only for modes having a large number of circumferential waves. These theories, moreover, do not take into account the effect on the frequency of the change during deformation of the magnitude and direction of the applied load. In this investigation, a bending theory presented by Herrmann and Armenakas is employed in re-examining the influence of initial uniform circumferential and axial stress on the frequency of vibrations of simply supported circular cylindrical shells. The results are compared with those of previous investigations. Author
