Local buckling and post-local buckling redistribution of stress in slender plates and sections

Thin-Walled Structures, 2006
Cold-formed open steel sections are comprised of component plates termed stiffened elements (webs) and unstiffened elements (flanges). The local buckling and post-local buckling behaviour of sections may be determined from the behaviour of the component plates.

Buckling of residually stressed plates: An asymptotic approach

Mathematics and Mechanics of Solids, 2013
We consider a residually stressed plate-like body having the shape of a cylinder of cross-section ω and thickness hε, subjected to a system of loads proportional to a positive multiplier λ. We look for the smallest value of the multiplier such that the plate buckles, the so-called critical multiplier.

Local buckling and flexural-torsional buckling with regard to residual stresses

Journal of Constructional Steel Research, 1992
Abstract The complex of strain-hardening of structural steel, residual stresses caused by technology, interaction of plate and lateral-torsional buckling significantly affects the stability conditions of beam-columns. Theoretical results, obtained by the energy method relying on the theory of plastic deformation, are compared with test results.

Vibration and Buckling of Shells under Initial Stresses

AIAA Journal, 1973
A new technique for designing a phase lead compensator on the S-plane has been presented in this work. This technique eliminates the need for trial and error cycles which are a feature of the present technique." It can be carried out in part through a graphical construction or in an entirely analytical way.

VIBRATION AND BUCKLING OF INITIALLY STRESSED CURVED BEAMS

Journal of Sound and Vibration, 1998
Summary: Equations of motion for curved beams in a general state of non-uniform initial stresses are derived using the principle of virtual work. The equations are adjusted to a generic expression by using appropriate transformations. The free vibration behaviours of the curved beams subjected to a combination of uniform initial tensile of compressive ...

Inelastic Buckling of Rings with Residual Stresses

Journal of the Engineering Mechanics Division, 1973
Circular rings are commonly fabricated by cold rolling long straight bars of desired cross sections to the required radii and then completing them with a single butt weld. This process induces significant amount of residual stress in a ring which affects its in-service performance.

Stress Analysis of Post-Buckled Sandwich Panels

Volume 3: Structures, Safety, and Reliability, 2018
The paper presents a method to assess stresses in sandwich plates with periodic microstructure in the post-buckling region. The fundamental assumption is that the microstructure is linear elastic and von Karman non-linearity is present only at macro-, i.e. panel-scale.

Stress, buckling and vibration of prismatic shells

9th Aerospace Sciences Meeting, 1971
A computer code for the general treatment of complex shells of revolution is applied to the analysis of prismatic shells such as oval cylinders, corrugated sheets, and longitudinally stiffened cylinders with stringer discreteness retained in the model.

Stresses in rock outside buckled layers

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1979
Abstract The author presents a theory of folding stresses in rocks, based on assumption of elastic equilibrium or slow viscous flow and a known fold geometry. The theory was first formulated in 1960–1961 and applied in practical problems. At this stage the general form of the solution is derived, applicable to arbitrary fold configurations.
