TLDR
In this paper, the authors considered simply supported edge conditions, for which the buckling modes consist of integer numbers of half sine waves in the two perpendicular directions, and showed that the lowest buckling mode in biaxial compression has a single half wave in an effectively short direction, or in both directions if the plate is effectively nearly square.Abstract:
Simply supported edge conditions are considered, for which the buckling modes consist of integer numbers of half sine waves in the two perpendicular directions. This note con siders the usual design case of specified load ratios. The lowest buckling mode in biaxial compression is shown to have a single half wave in an effectively short direction, or in both directions if the plate is effectively nearly square. The tension/compression case has a single half wave in the tension direction. The number of multiple half waves can be ap proximately determined to minimize numerical search computations.read more

Explicit local buckling analysis of rotationally restrained composite plates under biaxial loading
TL;DR: In this article, a variational formulation of the Ritz method is used to establish an eigenvalue problem for the local buckling behavior of composite plates elastically restrained along their four edges (the RRRR plates) and subjected to biaxial compression, and the explicit solution in terms of the rotational restraint stiffness (k) is presented.

Correlation Between some Stability Problems for Orthotropic and Isotropic Plates under Bi-Axial and Uni-Axial Direct Stress
TL;DR: In this paper, the authors considered four buckling problems: (a) a rectangular orthotropic plate, with all edges simply supported, subjected to compression on its ends and a known compression or tension on its sides; (b) the same as (a), but with the ends clamped and sides simply supported; (c) a rectilinear orthotropic (ROR) plate with both ends and sides clamped.
