| Abstract: | The coupling effects on two concentric cylindrical shells with periodic annular plates as well as entrained fluid were investigated theoretically.Expressions for the reactive forces by the annular plates were derived on the assumption that only quasi-longitudinal waves exist in the annular plates and an analytical expression for the outer shell was developed.Comparisons of numerical results for infinite two-walled cylindrical shell to measured data for a cabin model are in good agreement.Numerical results w... |
