Simple Bending Analysis of Laminated Plates by Large-Deflection Theory

Abstract

A closed-form solution is presented for the problem of laminated plates subjected to simple bending by the application of the nonlinear von Karman equations of heterogeneous anisotropic plates. The coupling effect between in-plane extension and transverse bending of cross-ply and angle-ply laminates on the cross-sectional distortion of the bent plates is studied. The results of the cases of two-layer com posite of orthotropic material are obtained, it shows that cross-ply of layers with high tensile moduli ratio can greatly reduce the peak-to- trough deflection of the cross section of a bent laminated plate.
