Thermoelastic Analysis of a Functionally Graded Rotating Thick-Walled Tube Subjected to Mechanical and Thermal Loads

摘要: A thermoelastic solution for the functionally graded rotating thick-walled tube subjected to axisymmetric mechanical and thermal loads is given in terms of volume fractions constituents. We assume that consists two linear elastic constituents fraction one phase a power function varied radial direction. By using assumption uniform strain field within representative element, theoretical solutions displacement stresses are presented. Based on relation average macroscopic composite material micromechanics, present method can avoid distribution regularities unknown overall parameters appeared existing papers, such as Young’s modulus, expansion coefficient, conductivity, density. The effects angular velocity, fraction, ratio coefficients, conductivities, densities systematically studied, which should help structural engineers scientists optimally design comprised inhomogeneous materials.
