Low Frequency Acoustics of Laminated Composite Axisymmetric Structures.
Abstract
A theory of low frequency sound radiation from and scattering by finite axisymmetric laminated composites is given. The structure is modelled by conical shell finite elements or axisymmetric solid finite elements. The surrounding fluid is modelled by the Helmholtz integral equation. Excitations are a time-harmonic mechanical force at a selected node or a plane wave at arbitrary incidence. Degrees of freedom other than those normal to the structure's exterior surface are removed by receptance coupling methods....Acoustic radiation, Acoustic scattering, Theory, Finite elements, Laminated composites.
