Advanced fiber-reinforced composite materials have been used for structural members because of their high specific strength and stiffness. A study is conducted on the stability of symmetric cross-ply laminated cylindrical shells under static and periodic external pressure of short duration. The cylindrical shell can withstand an impulsive load greater than the static buckling pressure if the loading duration is very short compared with the free vibration period of the laminated cylindrical shell in the first mode. The inevitability of dynamically unstable behaviors and the effects of various factors, such as load ratio, number of layers, stacking sequence, fundamental natural frequency, driving amplitude of the vibration and dynamic unstable mode, are analytically clarified.
