A Consistent Treatment of Bending of Anisotropic Laminated Plates

摘要

Stress based shear deformation theories for anisotropic laminated plates are difficult to implement because of the discontinuity of bending stresses at the ply interface. A model which uses displacement assumptions in conjunction with interlaminar stresses derived from equilibrium is investigated. Details of this approach are considered in conjunction with a [0°/90°]_s laminate under cylindrical bending. Resulting constitutive relations are shown to reduce to those of Reissner plate theory for the case of homogeneous, orthotropic plates
