Creep stresses have been evaluated for functionally graded rotating disk made up of orthotropic materials having variable thickness and density with the use of transition theory and generalized strain measure. The use of generalized strain measure with transition theory eliminates the use of adhoc conditions i.e. semi-empirical laws such as Norton’s law etc. From the analysis of circumferential stresses, it has been concluded that functionally graded rotating disk made up of isotropic material (Steel) is better alternative for engineering design as compared to that of orthotropic material (Barite and Uranium) because for functionally graded steel disk, circumferential stresses are less as compared to that for the functionally graded orthotropic disk.
