Abstract

A general displacement-based shear and transverse normal deformable plate theory is reviewed. Shear and transverse normal deformable plate theories suitable for cylindrical bending problems have been deduced from the general plate theory by introducing certain general functions of the transverse coordinate into the displacement field approximation. This theory takes into account the transverse shear and normal deformation effects and unifies most of the classical and shear deformable theories available in the literature.

A predictor-corrector method has been used for improving the accuracy of transverse stress analysis results and assessing the accuracy of composite plate/beam theories. In more detail, uniform shear deformable plate theory, parabolic shear deformable plate theory, general three-degree-of-freedom shear deformable plate theory, general four-degree- of-freedom transverse shear and normal deformable plate theory and general five-degree-of-freedom shear deformable plate theory are employed to improving their prediction performances of transverse shear and normal stresses.

By means of the assessment of plate theories for simply supported beams, general three-degree-of-freedom shear deformable plate theory, general four-degree-of-freedom transverse shear and normal deformable plate theory are applied for other sets of boundary conditions of cross-ply laminates subject to mechanical loading. General five-degree-of-freedom shear deformable plate theory is applied for angle-ply laminates subject to mechanical loading. In addition, general four-degree-of-freedom transverse shear and normal deformable plate theory is employed for cross-ply laminates subject to thermal loading. The numerical results of the present studies are compared with the corresponding exact solution results available in the literature.
