Thermoelectroelastic analysis of piezoelectric circular cylinders under extension, torsion, bending, pressuring, shearing, and temperature changes is presented. Referring to the cylindrical coordinates, the material is radially inhomogeneous and cylindrically anisotropic. Exact solutions are obtained for generalized plane problems of the piezoelastic cylinder with power-law radial inhomogeneity. For arbitrary radial inhomogeneity, two viable solution schemes are suggested. The analysis is useful for studying the responses of cylindrically anisotropic bodies of functionally graded materials subjected to thermoelectromechanical loading.
