FREE VIBRATION ANALYSIS OF SHELLS OF REVOLUTION

Abstract An efficient substructuring analysis method is presented for predicting the natural frequencies of shells of revolution which may have arbitrary shape of meridian, general type of material property and any kind of boundary condition. This method is developed in the context of first order shear deformation shell theory as well as the classical thin shell theory. The vibrational behaviours of a circular cylinder, an elliptic hyperboloid shell (modelling a cooling tower) and a complete spherical shell are investigated using this method.
