Thermo Creep Transition in Thin Rotating Non-Homogeneous Disc of Variable Thickness and Variable Density

Thermal creep stresses have been obtained for a thin rotating non-homogeneous disc of variable thickness and variable density, using Seth's transition theory. Non-homogeneity in the disc is considered due to radial variation of modulus of rigidity. Thickness and density are assumed to very along the radius. As a numerical example, it is found that an incompressible material whose rigidity and density decrease radially from the bore furnishes higher values of the tangential stress at the inner surface and hence increases the possibility of a fracture at the bore. The materials whose rigidity and density increase radially are preferable for manufacturing of the tapered disc components in presence of small temperature gradient.
