The analytical solution of steady-state asymmetric thermo-electro-mechanical loads of a
hollow thick infinite cylinder made of porous piezoelectric materials (2D-PPMs) based on
two-dimensional equations of thermoelasticity is considered. The general form of thermal and
mechanical boundary conditions is considered on the inside and outside surfaces. A direct
method is used to solve the heat conduction equation and the non-homogenous system
of partial differential Navier equations using the complex Fourier series and the powerexponential
law functions method. The material properties are assumed to depend on the
radial and circumferential variable and are expressed as power-exponential law functions
along the radial and circumferential direction.
