In this paper thermal buckling of FGM cylindrical shells under the influence of thermal loading uniform based on CLPT in simply support boundary conditions analyzed. At first the equations of equilibrium extracted with considering the Euler’s equations, next with apply second variations on strain energy, the stability equations will be obtained. Finally with zero insert this equation, the critical buckling load calculated. In the end the numerical results and the figures clearly shows analysis of this research in various positions
