Abstract
In this work a novel integral higher shear deformation theory (HSDT) which introducing the transverse shear effect is developed for thermoelastic bending analysis of Titanium/Zirconia power-law functionally
graded (P-FG) sandwich plates. This integral theory contains only four variable functions as against five in the
case of other HSDTs. The proposed model has a reduced number of equations and satisfies automatically the
free surface conditions (zero shear stresses) without using the shear correction factor. The P-FG sandwich plate
is assumed composed of the isotropic core and FG skins. The governing equations of are derived and resolved
via virtual work principle and Navier’s model. The accuracy of the proposed analytical model is confirmed
by comparing the results with those given by others model existing in the literature. Also, several parametric
examples are presented to show the thermoelastic bending response of the various symmetric P-FG sandwich
plates.
