Use of the Double-Sum Technique for Computing the Modal Response of Regularly Ribbed Cylinders.

Abstract

Recently an efficient technique was proposed for performing a Fourier transformation on integrands that are composed of aliased factors. In this report the proposed technique is utilized to perform Fourier transformations on quantities that pertain to the response of a regularly ribbed cylinder. The computations relate to Fourier transformations from the axial wavenumber domain to the axial spatial domain. The phenomena of aliasing and pass and stop bands are of particular interest. It is argued that the complementarity of the data, when presented in the two Fourier conjugate domains, may be a useful analytical (and experimental) tool.
