Abstract

A theoretical model for free vibration of orthotropic truncated conical shell with fluid load is presented. The solution for free vibration of truncated conical shell with fluid load is found by use of wave propagation approach and Galerkin method. The fluid loaded conical shell is divided into several segments and each small strip of conical shell is treated as circular cylindrical shell. The fluid load of conical shell is obtained by determining the fluid load of each cylinder. Thus, the fluid load acts on conical shell by parts. Numerical results for isotropic and orthotropic conical shells with fluid load or without fluid load are computed to illustrate the validity of the presented solution procedures.
