Thermoelastic response of functionally graded sandwich plates using a simple integral HSDT

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.
