Abstract:

A mathematical model is described for the sound scattering from a finite cylindrical shell with two endplates submerged in a fluid, subjected to an incident wave impinging on the shell from a source in an arbitrary direction. The effect of structural damping and rib-stiffeners on the monostatic scattered response of the structure is considered for a full range of incident wave angles over the nondimensional frequency range ka=0.1--30.
