The shell properties are assumed to vary\r\ncontinuously from the inner surface to the outer surface of the shell.\r\nThe equilibrium and stability equations are derived using the total\r\npotential energy equations, Euler equations and first order shear\r\ndeformation theory assumptions. The resulting equations are solved\r\nfor simply supported boundary conditions. The critical temperature\r\nand pressure loads are calculated for both short and long cylindrical\r\nshells. Comparison studies show the effects of functionally graded\r\nindex, loading type and shell geometry on critical buckling loads of\r\nshort and long functionally graded cylindrical shells.","references":null,"publisher":"World Academy of Science, Engineering and Technology","index":"Open Science Index 50, 2011"}
