“…Some of these papers are related to rotating FG disks. Leissa and Vagins [14] and Jain et al [15] optimized the distribution of stresses in rotating disks by varying elastic coefficient as a function of radius. Jain et al [16] and Zhou and Ogawa [17] presented an analytical method for analyzing rotating disks.…”

In the present paper, radial and hoop thermal and mechanical stress analysis of a rotating disk made of functionally graded material (FGM) with variable thickness is carried out by using finite element method (FEM). To model the disk by FEM, one-dimensional twodegree elements with three nodes are used. It is assumed that the material properties, such as elastic modulus, Poisson's ratio and thermal expansion coefficient, are considered to vary using a power law function in the radial direction. The geometrical and boundary conditions are in the shape of two models including thermal stress (model-A) and mechanical stress (model-B). In model-A there exists no pressure in both external and internal layers, and there is a temperature distribution considered as a second order function in the radial direction of the rotating disk. In this case, the temperature dependency of the material properties is considered and a hyperbolic type is assumed for the geometry of the disk. In model-B, there is a constant pressure only on the internal layer and a pressure on the internal layer of the disk without temperature distribution but with different types of surface profiles. Furthermore, the displacements and stresses for various power law indices (N) and angular velocities are calculated and compared to other results in the literature. The effect of varying thicknesses and dependency of material properties on temperature distribution is investigated.

“…Gowayed et al [15] used a sequential quadratic programming approach to optimally design a composite flywheel by varying reinforcements in the hoop and the radial directions. Jain et al [16] designed a constant thickness composite disk of uniform strength by radially tailoring the elastic moduli, and Güven et al [17] found the radial variation of elastic moduli to attain uniform radial stress in the disk. Fabien [18] studied the optimal design of a stacked-ply composite flywheel with fibers oriented either in the hoop or in the radial direction.…”

Taking Young's modulus, thermal expansion coefficient and density to be the functions of the radial coordinate, a closed form solution of rotating circular disks made of functionally graded materials subjected to a constant angular velocity and a uniform temperature change is proposed in this paper. Excellent agreement with the solution from Mathematica 5.0 indicates the correctness of the proposed closed form solution. Distributions of the radial displacement and stresses in the disks are determined with the proposed approach and how material properties, temperature change, geometric size and different material coefficients affect deformations and stresses is investigated.
