| Summary: | The effect of imposing linear thermal gradient on the steady state creep behavior of a rotating functionally graded Al-SiCp disc is investigated in the present study by using Sherby’s law. Mathematical model to describe steady state creep behavior in rotating disc made of isotropic Al-SiC composite in presence of linear thermal gradient in the radial direction has been formulated. The distributions of stresses and strain rates have been obtained. The creep response of a composite disc with uniform temperature has also been computed for comparison with the results obtained for thermally graded discs. The creep rates in a rotating thermally graded disc can be significantly reduced in presence of thermal gradients. |
