This paper deals with the problem of dynamic stability of angle-ply and cross-ply laminated cylindrical shells subjected to periodic axial compressive loading, external pressure and hydrostatic pressure. Several cases of the dynamic stability problem for composite laminated cylindrical shells are solved explicitly. The solutions for the prebuckling motion and the perturbated motion are obtained by the use of Galerkin's method. Calculations are carried out for composite laminated cylindrical shells and the instability regions are determined by utilizing Mathieu's equation. The inevitability of dynamically unstable behavior is proved analytically and the effects of various factors, such as static buckling, load ratio, number of layers, stacking sequence, vibrated amplitude, fundamental frequency, lamination angle, dimension of cylinder and dynamic unstable mode, are clarified.
