BUCKLING AND POST-BUCKLING BEHAVIOR OF A LARGE ASPECT RATIO ORTHOTROPIC PLATE UNDER COMBINED LOADINGS

Orthotropic plate theory has been increasingly used to model plate-stiffener combinations typical of those which are used in ship hulls. The behaviour of a thin plate with large deflections is described by two nonlinear partial differential equations of equilibrium and compatibility. The orthotropic form of these equations is derived and solved for a large aspect ratio plate with long edges simply supported and short edges fixed as boundary conditions. Buckling and post-buckling regions are investigated under combined loadings of lateral pressure, inplane edge compression and edge shear. Results are presented for virtual aspect ratios 1/1.5 to 1/6 and both isotropic and orthotropic plate properties in the form of design and behaviour charts.
