“…These materials which are mainly constructed to operate in high temperature environments find their application in aerospace, turbine motors, flywheels and gears just to Many studies conducted on FGMs are related to the analysis of thermal stress and deformation [3][4][5][6]. Durodola and Attia [7,8] provide a finite element analysis for FG rotating disks using commercial software.…”

In this paper, a semi-analytical investigation intended to determine the axisymmetric elastic response of functionally graded (FG) disks. The material properties of the disk are assumed to be graded continuously along the radial direction. An exponential function and the Mori-Tanaka scheme are used for estimating the effective material properties. Two kinds of functionally graded materials (FGMs) namely metal-ceramic and ceramic-metal are considered. Hollow disks are considered and the solutions for the displacements and stresses are given under appropriate boundary conditions. The effects of the material grading index and the geometry of the disk on the displacements and stresses are investigated. The results in metal-ceramic and ceramic-metal FGMs are compared. These results show that radial displacement in Ceramic-Metal functionally graded disks are smaller than those in Metal-Ceramic FG disks. These results suggest that a rotating functionally graded disk with concave thickness profile can be more efficient than the one with uniform thickness.

“…Vel and Batra analyzed the three-dimensional transient thermal stresses of the functionally graded rectangular plate (14) . We analyzed the transient thermal stress problems of a functionally graded circular plate (15) , a functionally graded thick strip (16) and a functionally graded rectangular plate (17) , where the thermal conductivity, the coefficient of linear thermal expansion and Young's modulus vary exponentially in the thickness direction, due to nonuniform heat supply. As exact analysis for shell type structures, the one-dimensional solutions for transient thermal stresses of functionally graded hollow cylinders and hollow spheres whose material properties vary with the power product form of radial coordinate variable were obtained (18), (19) .…”

This paper is concerned with the theoretical treatment of transient thermoelastic problem involving a multilayered hollow cylinder with piecewise power law nonhomogeneity due to uniform heat supply. The thermal and thermoelastic constants of each layer are expressed as power functions of the radial coordinate, and their values continue on the interfaces. We obtain the exact solution for the one-dimensional temperature change in a transient state, and thermoelastic response under the state of plane strain. Some numerical results for the temperature change, the displacement and the stress distributions are shown in figures.

“…At first, functionally graded materials were mainly employed in those areas relating to high-temperature environment, so thermoelastic analysis has always been the subject of researches from the beginning [1][2][3][4][5][6][7][8][9][10][11][12][13][14] . For example, Noda and coauthors [1][2][3] studied the thermoelastic problems of functionally graded plates, hollow annuli, and hollow spheres.…”

A thermoelastic problem of a circular annulus made of functionally graded materials with an arbitrary gradient is investigated. Different from previous works, our analysis neither requires a special form of the gradient of material properties nor demands partitioning the entire structure into a multilayered homogeneous structure. Instead, we propose a new method for solving the thermoelastic problem of a functionally graded circular annulus by transforming it to a Fredholm integral equation. The distribution of thermal stresses and radial displacement can be obtained by solving the resulting equation. Illustrative examples are given to show the effects of varying gradients on the thermal stresses and radial displacement for given temperature changes at the inner and outer surfaces. The results indicate that the thermal stresses can be relaxed for specified gradients, which is beneficial to design an inhomogeneous annulus to maintain structural integrity.
