Abstract

The method of wave function expansion is adopted to study the three dimensional scattering of a plane progressive harmonic acoustic wave incident upon an arbitrarily thick-walled helically filament-wound composite cylindrical shell submerged in and filled with compressible ideal fluids. An approximate laminate model in the context of the so-called state space formulation is employed for the construction of T-matrix solution to solve for the unknown modal scattering coefficients. Considering the nonaxisymmetric wave propagation phenomenon in anisotropic cylindrical components and following the resonance scattering theory (RST) which determines the resonance and background scattering fields, the stimulated resonance frequencies of the shell are isolated and classified due to their fundamental mode of excitation, overtone and style of propagation along the cylindrical axis (i. e., clockwise or anticlockwise propagation around the shell) and are identified as the helically circumnavigating waves. The solution is particularly used for the quantitative sensitivity analysis of excited resonance frequencies of an air-filled and water submerged Graphite/Epoxy cylindrical shell to the perturbation in the material’ s elastic constants.
