Sound Wave Scattering From an Elastic Spherical Shell
Abstract
The Helmholtz integral equation may be formulated by combining the scalar wave equation and Euler's equation for motion within a fluid. The solution to this integral equation yields the radiated pressure from a submerged vibrating body. The solution obtained from applying Hamilton's variational principle governs the response to a given surface pressure excitation. These two solutions may be used in conjunction to investigate the scattering of incident sound waves from shell-like bodies. In this report, the scattering from a submerged steel spherical shell having a thickness to radius ratio of 0.01 is investigated for ka values up to 8....
