Three-Dimensional Stress Analysis of Rotating Hollow Cylinders

Abstract

This paper describes an analytical method of the stresses and deformations of the rotating finite hollow cylinders using the method suggested in Ref. (5). Particularly, the studies on the effect of the wall-thickness on the stress distributions and deformations of rotating finite hollow cylinders were made in detail with the aid of the computer. The obtained results are as follows : (1) With the value of a/b increased to 1.0, the stress distributions are almost similar to the well-known two-dimensional results, where a/b is the ratio of the inner to the outer diameter. (2) The shear stress reaches its maximum in the middle of the inner surface, and increases slightly when the ratio of a/b becomes greater. (3) In the case of a stick cylinder of a/b=1/8, the wall-thickness increases by rotation, but on the other hand in the case of a thin cylinder, it decreases.
