Finite element post‐buckling analysis for frames

International Journal for Numerical Methods in Engineering, 1977
AbstractPresented in this paper is a direct method of analysis of the elastic non‐linear behaviour of frames. Emphasis is given to the method's capability of tracing the post‐buckling path from a bifurcation point although the method can also trace the non‐linear behaviour of frames with eccentricities.

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.

Post-buckling and vibration of post-buckled rotating pre-twisted FG microbeams in thermal environment

Thin-Walled Structures, 2019
Abstract In this paper, comprehensive studies on the size-dependent thermal post-buckling and coupled bi-directional transverse-longitudinal free vibration behavior of post-buckled rotating pre-twisted functionally graded (FG) microbeams in thermal environment are presented.

Post‐buckling Equilibrium of Hyperstatic Lattices

Journal of Engineering Mechanics, 1985
Post‐buckling equilibrium paths of complex, elastic, hyperstatic, pin‐jointed lattices composed of slender members are studied under the aspect of finite deformation using a new simplified theory, which is presented in matrix formulation. A general numerical procedure is developed on a digital computer for the solution of the reduced equilibrium ...

Post-Buckling of Redundant Rectangular Beams

Journal of the Engineering Mechanics Division, 1975
The post-buckling behavior of redundant single-span rectangular members is investigated using an equilibrium approach and large potential reserves of strength are shown to exist. In some cases, loads up to three times the initial buckling loads can be supported before the deformations and stresses exceed acceptable limits.

Post-Buckling of Axially Compressed Plates

Journal of the Structural Division, 1972
Aluminum square tubular sections subjected to axial compression generally exhibit a significant reserve of strength above the critical stress levels associated with plate buckling. Load-transverse deflection curves averaged over the four faces of each of six specimens with different slenderness ratios B (width to thickness) validates the nature of ...

Thermal post-buckling of circular plates

Computers & Structures, 1984
The thermal post-buckling behaviour of isotropic circular plates has been studied in this paper by a simple finite element formulation. The accuracy of the solution by finite element method is established through a solution by the Rayleigh-Ritz method for simply-supported circular plates.

Post-Buckling of Geometrically Imperfect Plates

Journal of the Structural Division, 1972
Explicit expressions are derived for the collapse and elastic post-buckling of simply supported, geometrically imperfect plates with stress-free edges. For the purposes of design, such plates can be taken as representative of the stiffened compression elements of thin-walled structural sections.
