     three-dimensional thermo-elastic analysis of a functionally graded cylindrical shell with piezoelectric layers under the effect of asymmetric thermo-electro-mechanical loads is carried out. numerical results of displacement, stress and thermal fields are obtained using two versions of the differential quadrature methods, namely polynomial and fourier quadrature methods. material properties of the shell are assumed to be graded in the radial direction according to a power law but the poisson’s ratio is assumed to be constant. shells are considered to be under the effect of the pressure loading in the form of cosine and ring pressure loads, electric potentials and temperature fields. numerical results for various boundary conditions are obtained and the effects of the thickness of piezoelectric layers, grading index of material properties and the ratio of the thickness to the radius of the shell on these results is presented.
