The classical plate theory neglects transverse shear strains, which brings about considerable errors in deflections, strains and stresses for the analysis of laminated plates. Now, a simple higher-order theory proposed by Reddy, which is one of the higher-order shear deformation theories of laminated plates, is widely used. In this paper, a uniformly loaded thick circular laminated plate with a clamped edge is analyzed using 3-dimensional finite-deformation theory, and from this result, the applicability of the higher-order shear deformation theory to both infinitesimal deformations and large deformations is examined. As a numerical method, the 3-dimensional finite element method which is formulated using the incremental theory based on the convected coordinates is used.
