The closed-form solution is employed to obtain the critical buckling loads of functionally graded cylindrical shells under mechanical loads. The Young's modulus of shell is assumed to vary as a power form of the thickness coordinate variable. The equilibrium and stability equations are derived based on classical shell theory. The influences of dimension ratio, thickness ratio and the inhomogeneity parameter on the critical buckling loads are studied. The results are verified with the known data in the literature.
