Abstract
A new laminated plate thermoelastic theory upon a new mixed variationa l principle proposed by Reissner [Int. J. Numer. Meth. Engng 20, 1366- 1368 (1984)] is developed to study the thermal stresses of laminated c omposite plates. Across each individual layer, piecewise linear contin uous displacement and quadratic transverse shear stress distributions are assumed. The temperature variation through the thickness is consid ered to be linear. The theory is examined by applying it to the proble m of rectangular plate bending. Some numerical results for thermal str esses and deflections are compared with those obtained using the high- order and the first-order zig-zag thermoelastic theories.
