Layerwise Theory of Bending of Symmetric Laminates with Isotropic Plies

摘要

SEVERAL theories on analysis of laminated plates are reported in literature (see a few recent review papers: [1-5]). They are generally based on ply and/or plate-element equilibrium equations. Such theories in the present study involve coupling of bending and torsion, whereas exact solutions of 3-D problems within small-deformation theory are uncoupled. Recently, this coupling in analysis of a homogeneous plate was eliminated through the introduction of an auxiliary harmonic function in the representation of in-plane (face-parallel) displacements in Kirchhoff's theory in [6] and in an iterative method briefly described in [7]. In the present work, this iterative procedure is extended to a laminated plate.
