Abstract : The paper deals with the case of the axisymmetrical (n=0) forced vibrations of a thin cylindrical shell of finite length submerged in an acoustic fluid. Numerical results are given for several structural models which may later be utilized to obtain test results. The superposition of the pressure fields obtained from the band excitations may be used to evaluate the pressure fields in the fluid which are produced by harmonic point loadings on the shell, or by loadings over small finite areas of the structure. Such results will be utilized to attempt the prediction of sound fields for a series of tests on the thin elastic cylindrical shell models of finite length.
