Mh. Marcus et A. Sarkissian, RIB RESONANCES PRESENT IN THE SCATTERING RESPONSE OF A RIBBED CYLINDRICAL-SHELL, The Journal of the Acoustical Society of America, 103(4), 1998, pp. 1864-1866
The presence of ribs in an evacuated, finite cylindrical shell, placed
in a fluid medium, produces highlights in its scattering response at
certain resonant frequencies. These resonances are identified from the
end-incident bistatic response of a ribbed cylindrical shell and are
shown to be produced by the flexural vibrations of individual ribs sat
isfying the boundary conditions of an annular plate.
