Buckling stresses of simply supported rectangular flat plates in shea
Year: 1947
Abstract: INTRODUCTION
In reference 1 Timoshenko presents a solution for the buckling stresses of simply supported rectangular flat plates in shear. Timoshenko considered only the equations which permitted a buckle pattern symmetric about the midpoint of the plate. This limitation led to a small error in the critical stress in several cases in which the governing buckle pattern was antisymmetric instead of symmetric.
The buckling stresses have been determined more correctly than in reference 1 by considering both the symmetric and the antisymmetric buckle patterns. Through the use of the matrix iteration method described in reference 2 and by a proper choice of the terms in the series representing the deflection, more accurate results were obtained. The theoretical analysis given in the appendix is a brief summary of the derivation given in reference 1.
