TLDR
In this article, the results of a numerical evaluation of a characteristic equation derived in Part I, appropriate to free harmonic waves propagated along a hollow cylinder of infinite extent, were given for some representative cylinders covering the entire range from thin shells to solid cylinders.
Abstract: 
The results are given of a numerical evaluation of a characteristic equation derived in Part I, appropriate to free harmonic waves propagated along a hollow cylinder of infinite extent. This equation is evaluated for some representative cylinders covering the entire range from thin shells to solid cylinders, and the results are compared with the corresponding results of a shell theory. Observations are made regarding the variation of the frequency spectrum with the physical parameters, as well as the range of applicability of shell theories.

Resonant wave propagation in gun tubes with eccentric bores

H.F. Tiersten, +1 more
- 01 Feb 1995 - 
TL;DR: In this paper, an analysis of the steady-state vibrations of gun tubes with eccentric bores is performed entirely within the framework of three-dimensional linear elasticity, and the resulting solutions clearly exhibit the coupling between the extensional and flexural motions.
