Thermo-electromechanical behavior of functionally graded piezoelectric hollow cylinder under non-axisymmetric loads
First Online: 05 June 2015
This paper presents an analytical solution of a thick walled cylinder composed of a functionally graded piezoelectric material (FGPM) and subjected to a uniform electric field and non-axisymmetric thermo-mechanical loads. All material properties, except Poisson’s ratio that is assumed to be constant, obey the same power law. An exact solution for the resulting Navier equations is developed by the separation of variables and complex Fourier series. Stress and strain distributions and a displacement field through the cylinder are obtained by this technique. To examine the analytical approach, different examples are solved by this method, and the results are discussed.
