Abstract
In this paper, an enhanced Reddy's theory is proposed for sandwich plates subjected to varying temperature fields. Based on the enhanced Reddy's theory, analytical formulations and solutions are obtained by means of the principle of virtual displacement and Navier's technique. Typical examples are considered to present the effects of transverse normal strain and temperature profile on the stress distributions of sandwiches. Numerical results show that transverse normal strain as well as the temperature profile across the thickness direction has significant influence on the thermal stresses of sandwich plates.
