In this study, the dynamic stability problem of a laminated circular cylindrical shell composed of layers of nonhomogeneous orthotropic elastic materials with elasticity moduli and density varying piecewise continuously in the thickness direction under the effect of an axial compression varying with a power function of time, is considered. At first, the fundamental relations and the dynamic stability equations of a nonhomogeneous orthotropic elastic cylindrical shell with n layers is set up. Applying Sachenkov's method [1], the formulas for the dynamic and static critical loads and the corresponding wave number and dynamic factor are obtained. The results are verified using previous works.
