Eigenvalue analysis of cylindrically curved steel panels under pure shear
Abstract In this paper, an extensive numerical study is performed with the aim to investigate the elastic buckling behavior of simply supported cylindrically curved steel panels subjected to a pure shear load. The main objective is to understand the influence of geometrical parameters, such as curvature and aspect ratio, but also of the edge in-plane constraints. Finally, a new formula is proposed, which allows simple and accurate estimation of the critical shear stress of unstiffened curved panels with three different types of edge constraints, for various curvatures (1 < Z ≤ 100) and various aspect ratios (up to 5).
Highlights Cylindrically curved panels subjected to shear load show very complex behavior. Buckling mode depends on curvature Z, aspect ratio α and in-plane edge constraints. Proposed formulae enable accurate prediction of the shear buckling coefficient k τ. Formulae can replace the outdated and impractical NASA monographs. Formulae extend EN1993-1-5 to a wide range of the curvature parameter (Z ≤ 100).
