Abstract

Response and sound radiation characteristics of a three-layered cylinder with equispaced (periodic) axial stiffeners are obtained using the "wave" approach. A two-dimensional situation with no variation in the axial direction is considered. Numerical results are presented for the case of three stiffeners, which are assumed to prevent both radial and tangential displacements of the base layer. The pressure harmonics exciting various modes are analyzed. Three different types of interior, namely, totally resonant or absorbent and partially absorbent, are investigated and their effects on the response and sound power radiation are studied.
