Abstract
A new high-order laminated plate thermoelastic responses theory, which is based on a new mixed variational principle proposed by Reissner (1 984) and accounts for transverse shear and transverse normal strains, is developed to study the thermoelastic behavior of a laminated compos ite plate. To this end, a zig-zag-shaped C0 function and Legendre poly nomials are introduced into the approximate displacement distributions across the plate thickness. The thickness variation of temperature is considered to be linear. The theory is examined by applying it to the thermal bending problem of cross-ply rectangular plates. The numerica l results of central deflection and thickness variation of in-plane an d transverse thermal stresses are obtained for symmetric and antisymme tric cross-ply plates.
