Buckling of thin-walled columns accounting for initial geometrical imperfections

International Journal of Non-Linear Mechanics, 2017
The paper is devoted to the effect of some geometrical imperfections on the critical buckling load of axially compressed thin-walled I-columns. The analytical formulas for the critical torsional and flexural buckling loads accounting for the initial curvature of the column axis or the twist angle respectively are derived.

Vibration analysis of stiffened plates with initial geometric imperfections

Proceedings of the Institution of Mechanical Engineers, Part M: Journal of Engineering for the Maritime Environment, 2020
This paper presents the vibration analysis of stiffened plates with initial imperfections, using both conventional and super finite element methods. Von Karman theory was utilized so as to formulate the plate element. Eccentricity of the stiffeners is also taken into account and they are not limited to be placed on nodal lines.

Measurement of the geometric initial imperfections in diaphragms

Thin-Walled Structures, 1992
Abstract A method, using a new surveying technique, is used for the measurement of the geometric initial imperfections in box girder diaphragms. The method, accurate to ±0·1 mm , may be used on diaphragms contained in a box girder where contact with the surface of the diaphragm is difficult or impossible or inadvisable due to the presence of ...

On the Choice of Initial Geometric Imperfections in Externally Pressurized Shells

Journal of Pressure Vessel Technology, 1999
Localized and global, of eigenmode type, initial geometric imperfections were superimposed on perfect torispherical, ellipsoidal, and toroidal shells of circular and elliptical cross section. Reduction of the load-carrying capacity was then calculated numerically for various geometries and the yield point of material which was assumed to be mild steel.
