Abstract:

The plate theory recently developed by Levinson is extended to laminates. Closed-form solutions of this theory, as well as those of Reissnet-Mindlin plate theory with appropriate shear correction, Seides discrete-layer plate theory, and Lo, Christensen, and Wus higher-order theory are all compared with Paganos elasticity-theory solution for the cases of cylindrical bending of a single orthotropic layer and a symmetric cross-ply 0 deg90 deg0 deg laminate consisting of three equal-thickness layers. Quantities compared are maximum plate deflection, bending stress distribution, and transverse shear stress distribution. Author
