The abrupt change in material properties across the interface between discrete layers in composite structures can result in large interlaminar stresses leading to delamination. One way to overcome these adverse effects is to use "functionally graded materials" which are inhomogeneous materials with continuously varying material properties. There are several three-dimensional (3D) solutions available for the thermoelastic analysis of inhomogeneous plates. Most of these studies have been conducted for laminated plates that have piecewise constant material properties in the thickness direction. Rogers et al. [1] have employed the method of asymptotic expansion to analyze 3D deformation of inhomogeneous plates.
