Abstract

The purpose of this study is to derive an equation to evaluate the elastic buckling strength of thin plates under flexural shear and axial forces. Well-known evaluation methods consider bending as constant bending. However, under flexural shear, bending will not be constant bending. Moreover, currently used methods do not properly distinguish between bending stress and shear stress. This is because these variables are not always independent of each other. The validity of these methods has, therefore, not been adequately verified. In this study, we investigate the validity of these methods, and for cases in which bending cannot be regarded as constant bending, we propose a new method.

► Stress separation concept for plate buckling under combined stresses is proposed. ► In proposed method, stresses are separated into “flexural-shear” and “compression”. ► Proposed method can evaluate the buckling strength more exactly.
