Sound Radiation from Infinite Laminated Composite Shell with Periodic Rib Stiffening
Abstract
A theory of sound radiation from an infinite cylindrical shell which is stiffened periodically by ribs is given. Both shell and ribs are laminated composites. The shell is modelled by the differential equations of a thin shell theory. The flexible ribs, which exert both forces and moments on the shell's surface, are modelled by thin conical shell finite elements; degrees of freedom other than those at the shell's surface are removed by receptance methods. Excitations are time-harmonic mechanical forces at arbitrary points on the shell's surface and ribs, and acoustic monopoles in the exterior and interior fluids....
