A quasi-3D hyperbolic shear deformation theory is presented for the bending behaviour of simply supported Functionally Graded (FG) ceramic-metal sandwich beams. The equations of motion are derived from total potential energy principle and the analytical solutions presented are based on the assumption of a simple support beam end conditions. The effects of varying power law index values and span-to-depth ratio on the static behaviour of two types (Type A- FG skins and homogeneous core and Type B - homogeneous skins and FG core) of FG sandwich beams are investigated in the present work. Numerical results from the present theory are compared with other theories to show the effect of the inclusion of traverse normal strain on the deflections and stresses.
