Abstract

The present study deals with the linear elastic analysis of rotating cylindrical pressure vessels. The vessels are made up of one directional functionally graded material (FGM), in which mechanical and physical properties are varying along the radial direction. The analysis is carried out using finite element method which is based on the principle of stationary total potential (PSTP). Material properties are graded according to the Mori-Tanaka distribution law and ceramic-metal as well as metal-ceramic both the types of FGMs are considered. The effects of the gradation of material properties on the stress and deformation behavior of the vessels are investigated and a comparison of deformation and stresses for different values of grading index is presented. The results obtained are in good agreement with the established reports and show that there is a significant variation in stresses and deformation behavior of the FGM vessels as compared to homogeneous vessels. Further it is observed that metal-ceramic FGM vessel having n = 0.5 has the lowest overall stresses, and therefore can be most effectively employed for the rotating cylindrical pressure vessels.
