✦ Synopsis

The problems of the vibration of rotating cylindrical shells are solved by using nine-node super-parametric "nite element with shear and axial deformation and rotatory inertial. The non-linear plate-shell theory for large de#ection is used to handle the cylindrical shell before it reaches equilibrium state by centrifugal force. The e!ects of Coriolis acceleration, centrifugal force, initial tension and geometric non-linearity due to large deformation are considered in this model. Eight categories of mode of a rotating thick cylindrical shell are presented. The e!ects of rotation on di!erent three-dimensional modes of cylindrical shell are discussed in detail.
