An exact solution procedure is presented for solving free vibrations of a rotating thick laminated composite circular cylindrical shell. Based on the thick lamination shell theory, equations of motion and boundary conditions are obtained from the stationary conditions of the Lagrangian. The equations of motion are solved exactly using a power series expansion for symmetrically laminated cross-ply shells. Frequencies and mode shapes of the shells with both ends clamped and both ends freely supported are presented, showing their variations with changes of rotating angular velocity, number of laminae and other parameters, and the effects of shear deformation and rotary inertia are discussed by comparing the results from the present theory with those from the classical lamination shell theory (thin lamination shell theory).
