Abstract

Using the infinitesimal theory of elasticity and analytical formulation, displacements and stresses based on the high-order SHEAR DEFORMATION THEORY (HSDT) is presented for axisymmetric thickwalled cylinders made of functionally graded materials under internal and/or external uniform pressure. The material is assumed to be isotropic heterogeneous with constant Poisson’s ratio and radially varying elastic modulus continuously along the thickness with a power function. At first, general governing equations of the FGM THICK CYLINDERS are derived by assumptions of the highorder SHEAR DEFORMATION THEORY. Following that, the set of non-homogenous linear differential equations with constant coefficients, for the cylinder under the generalized clamped-clamped conditions have been solved analytically and the effect of loading and inhomogeneity on the stresses and displacements have been investigated. The results are compared with the findings of both first-order SHEAR DEFORMATION THEORY (FSDT) and finite element method (FEM). Finally, the effects of higher order approximations on the stresses and displacements have been studied.
