ABSTRACT. In this paper we investigate stresses and displacement in thin nonhomogeneous rotating disc has been derived by using Seth's Transition theory and results have been discussed and depicted graphically. Non-homogeneity is assumed due to the variation of modulus of rigidity. As a numerical example, it has been seen that in the presence of non-homogeneity having values k > 0 at the bore, reduces stresses, displacement and the angular speed as compare to lesser value i.e. k <0 of nonhomogeneity. Radial stresses maximum at the internal surface.
