Analytic Deformation and Stresses Solutions of Functionally Graded Rotating Disk under Mechanical and Thermal Load

Abstract

This article presents analytical solutions for radial displacement and stresses of thin-walled functionally graded rotating disk subjected to pressure and temperature difference on its boundary surfaces. The thickness, elasticity modulus, material density, thermal expansion and thermal conduction coefficients of disk are represented by exponential forms of radial variable. Numerical results of radial displacement and stresses are shown in figures. Separate and combined effects of both pressure and temperature difference on radial displacement and stresses will be discussed graphically.
