Dynamic Displacements and Stresses in a Circular Cylindrical Shell of Finite Length with Both Ends Clamped Which is Subjected to Concentrated impulsive Loads

Abstract

In this paper, the dynamic displacements and stresses in a circular cylindrical shell of finite length with both ends clamped, which is suddenly subjected to radial concentrated loads on its surface, are analyzed on the basis of Flugge's shell theory with use of the Laplace transformation. As a result, it is shown that Donnell's shell theory, which is treated in the previous paper, yields good results if the length of the shell is short or the thickness is thin using Flugge's theory as the standard of comparison, and the values of the dynamic maximum stresses are scarcely affected by the axial and circumferential inertia forces of the shell but the values of the lowest frequencies and the transient responses of the stresses are much affected thereby.
