摘要

In this paper a thick short length hollow cylinder made of functionally gradedrnmaterials (FGMs) under hydrostatic internal pressure is considered. Three differentrntypes of functionally graded material behaviours are investigated. Two of them arernone dimensional FGMs and material properties vary through the radial direction.rnThird type is two dimensional FGMs and material properties vary through both thernradial and the axial directions. Graded Finite Element Method based on Rayleigh-rnRitz energy formulation is applied to study the elastic analysis of FG thick hollowrncylinders. Different types of displacements and stresses for a cylinder with simplyrnsupported end conditions are studied. To compare the model with the existingrnliterature, the result of an infinite FG thick hollow cylinder under the same loadingrnare obtained and it shows very good agreement.
