Static instability of rectangular orthotropic panels subjected to uniform in-plane loads and deflection-dependent lateral loads

Abstract

Summary. Various analyses are presented for orthotropic and isotropic panels from which several elastic stability characteristics can be obtained. The loadings considered are biaxial in-plane compression and lateral loads which are dependent on the panel deflections (typically aerodynamic loadings). The panels are assumed to be resting on an elastic foundation to increase the generality of the problem. The analyses are valid for panels whose edges experience no lateral deflection but which are in general elastically restrained against rotation. The application of the analyses to particular configurations is shown and for certain isotropic panels correlation with experiment is found.
