COMPUTATION OF THE MODAL RESPONSE OF REGULARLY RIBBED CYLINDERS

Recently an efficient technique was proposed for performing a Fourier transformation on integrands that are composed of aliased factors. In this paper the proposed technique is utilized to perform Fourier trans formations on quantities that pertain to the response of a regularly r ibbed cylinder. The computations relate to Fourier transformations fro m the axial wave-number domain to the axial spatial domain. The phenom ena of aliasing and pass bands and stop bands are of particular intere st. 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.
