Özet
Functionally graded materials (FGM) belong to advanced composite materials class whose mechanicalproperties vary continuously from one surface to another at macro level. Thick walled annular structuresare widely used in industry as nuclear reactors, long pipes used for carrying gases/oil, pressure vesselsetc. Elastic analysis of FG thick walled cylindrical and spherical pressure vessels subjected only to internalpressure are studied. The material properties (Young’ s modulus-Poisson’ s ratio) are assumed to obey thepower-law function through the wall thickness. Under these assumptions the governing equations of the FGvessels become a two-point boundary value problem. The analytical solution of such an equation can notbe obtained except for simple grading functions. Complementary Functions Method is performed to solvegoverning equation in order to obtain displacement and stress distributions depending on inhomogeneityparameters.
