Stress Analysis of Rotating Cylindrical Pressure Vessel of Functionally Graded Material by Element Based Material Gradation

Abstract

Abstract
The present study aims at the elastic analysis of rotating cylindrical pressure vessels made of functionally graded materials (FGMs), by element based gradation. Material properties of the shells vary in radial direction according to exponential distribution law. Ceramic-metal and metal-ceramic, both the types of FGM are considered and the effects of gradation of material properties on stress and deformation behavior of the shells are investigated. Further, a comparison of deformation and stresses for different values of thickness parameters in ceramic-metal and metal-ceramic shell is made. Results obtained show that there is a significant variation in stresses and deformation behavior of the FGM shells for different values of thickness parameter.
Keywords: Functionally graded material (FGM), elastic stress analysis, cylindrical pressure vessel, rotating shell, element based material gradation
