THERMOELASTIC ANALYSIS OF FUNCTIONALLY GRADED ANNULAR ROTATING DISC

This study deals with thermoelastic analysis of annular rotating disc made of functionally graded materials. Material properties are assumed to vary along radial direction according to power-law function, and the Poisson's ratio is constant. A gradient parameter is chosen between -0.5 to 0.5. When gradient parameter equals to zero, the disc becomes isotropic disc case. The distributions of radial and tangential stresses on the disc are obtained for various gradient parameter by means of the diverse elasticity modulus, thermal conductivity, thermal expansion coefficient and density.
