Creep Analysis of an Isotropic Linearly Decreasing Functionally Graded Rotating Disc at Linearly Increasing Temperature

Tania Bose

The present study investigates steady-state creep analysis of thermally graded isotropic rotating disc made of linearly varying particle reinforced functionally graded material using threshold stress based creep law. The stress and strain rate distributions have been calculated for the discs rotating at linearly increasing temperature from inner to outer radii with the help of von Mises' yield criterion. The results are displayed and compared graphically in designer friendly format for the said temperature profile with uniform temperature. A small variation is observed for radial and tangential stresses for said thermal gradations. However, the strain rates vary significantly in the presence of thermal gradation as compared to a disc having uniform temperature. A functionally graded rotating disc with linearly increasing thermal profile can be more efficient than those with uniform distribution as observed from the study.
