Free vibration and buckling of rotating prestressed anisotropic cylindrical shells are investigated. Torque, external pressure and axial compression load are considered as the prestresses. The basic equations are derived from Hamilton's principle, depending on the Flugge-type shell theory. The equations of motion can be separated into the quasi-static and dynamic ones, i.e., the equations in the steady rotating state and those in the vibrating state. By the modified Galerkin's method, frequency analysis is carried out for four boundary conditions. Numerical results are compared with previous results for simple cases, and the validity of the present analysis is ascertained. Then the general cases with the influence of anisotropy and prestresses are analyzed, and those effects on the frequency and buckling characteristics are examined.
