A simple and accurate two noded beam element is presented for the static thermo-elasto analysis of the beams made of functionally graded materials(FGMs).The formulation of this FG beam element is based on a refined third-order shear deformation beam theory and the quasi-conforming element technique.The material properties of FG beams are assumed to vary according to a power-law distribution through the beam thickness in terms of the volume fractions of the constituents.The influence of temperature on Youngs modulus and coefficients of thermal expansion is taken into account.The stiffness matrix of the resulting FG beam element is given explicitly,which leads to the present FG beam element is very computational efficient.The accuracy of numerical results given by the proposed models is validated against the results reported in the literature or the 2D finite element results solved by the authors.
