Formation of a new kind of advanced material type from polar orthotropic materials obeying certain functional material grading rules has gained a great importance lately. In this study, a circular annulus rotating at a constant angular velocity and made of such kind of advanced materials having the same inhomogeneity index for both elasticity moduli and material density is studied analytically. Governing equation in terms of radial displacement is derived from the elasticity theory under axisymmetric conditions and plane stress assumption for such structures. After deriving closed-form solutions, effect of the aspect ratio (inner radius/outer radius) of a rotating circular annulus with uniform thickness on the dimensionless elastic field is investigated. It is observed that both the aspect ratio and inhomogeneity index of a simple power-law material grading rule have significant impacts on the linear elastic response arising out of rotation of the annulus at a constant angular velocity.
