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.

Elastic orbital angular momentum transfer from an elastic pipe to a fluid

TL;DR: In this article , the authors experimentally observe the transfer of elastic orbital angular momentum from a hollow elastic pipe to a fluid in which the pipe is partially submerged, in an elastic analogue of Durnin's slit-ring experiment for optical beams.

Computing borehold modes with spectral method

TL;DR: In this paper, a spectral method for cylindrically layered media consisting of an arbitrary number of solid elastic and fluid layers is proposed, which discretises the underlying wave equations with the help of spectral differentiation matrices and solves the corresponding equations as an generalized eigenvalue problem.
