Assumptions of thin stiff layers and anti-plane core, which are usually made in the analysis of sandwiches, have been eliminated in the present formulation.

The displacement field contains the same number of dependent variables as in the first-order shear deformation theory, but accounts for continuity of in-plane displacements and transverse shear stresses across each layer interface. Exact closed-form solutions of symmetric cross-ply laminates are obtained and the results are compared with other theory solutions. A coefficient f3 including effects of transverse shear deformation on critical temperature and critical load is introduced.
