| Abstract: | The free vibration of a multi layered cylindrical shell submerged in an irrotational, inviscid and compressible fluid is studied. The hydrodynamic forces are considered in the motion equations of the shell and the flow field is described by the wave equation. The coupled equations are simplified using suitable displacement functions and velocity potential function and then numerically solved. The frequency characteristics of several shells with different layer configurations have been found. |
