“…They used standard type Euler-Cauchy equations in order to solve the problem. Elastic analysis of Internally pressurized thick walled spherical pressure vessels of FGMs was analyzed elastically by You et al [6]. Two types of pressure vessel are adopted in their study: one consists of two homogeneous layers near the inner and outer surfaces of the vessel and functionally graded layer in the middle; the other consists of the functionally graded material only.…”

Functionally graded materials (FGM) belong to advanced composite materials class whose mechanical properties vary continuously from one surface to another at macro level. Thick walled annular structures are widely used in industry as nuclear reactors, long pipes used for carrying gases/oil, pressure vessels etc. Elastic analysis of FG thick walled cylindrical and spherical pressure vessels subjected only to internal pressure are studied. The material properties (Young' s modulus-Poisson' s ratio) are assumed to obey the power-law function through the wall thickness. Under these assumptions the governing equations of the FG vessels become a two-point boundary value problem. The analytical solution of such an equation can not be obtained except for simple grading functions. Complementary Functions Method is performed to solve governing equation in order to obtain displacement and stress distributions depending on inhomogeneity parameters.

“…Although there are several papers in the elastic analysis of FGM spherical pressure vessels in the literature (You et al, 2005;Dai et al, 2006;Chen and Lin, 2008), elastic-plastic stress analysis of FGM spherical pressure vessel is not such a customary study. Sadeghian and Ekhteraei (2011) studied the thermal stress analysis for an FGM spherical pressure vessel made of elastic-perfectly plastic and power law material model.…”

A new elastio-plastic stress solution in axisymmetric problems (rotating disk, cylindrical and spherical vessel) is presented. The rotating disk (cylindrical and spherical vessel) was made of a ceramic/metal functionally graded material, i.e. a particlereinforced composite. It was assumed that the material's plastic deformation follows an isotropic strain-hardening rule based on the von-Mises yield criterion. The mechanical properties of the graded material were modeled by the modified rule of mixtures. By assuming small strains, Hencky's stress-strain relation was used to obtain the governing differential equations for the plastic region. A numerical method for solving those differential equations was then proposed that enabled the prediction of stress state within the structure. Selected finite element results were also presented to establish supporting evidence for the validation of the proposed approach.
