Localization of buckling modes in plates and laminates

Composite Structures, 2015
Abstract We use the Mindlin plate theory and the finite element method to delineate the effect of fixing points on a transverse normal to the mid-surface of the plate on the localization of buckling modes in clamped–clamped rectangular plates made of linear elastic, homogeneous and either isotropic (monolithic) or orthotropic (fiber-reinforced ...

Coupled modes of elastic buckling

Journal of the Mechanics and Physics of Solids, 1967
Abstract I t is shown that when the critical loads corresponding to the modes of buckling of a two-degrees-of-freedom system are equal, or nearly so, then elastic post-buckling involves coupling between the modes. The forms taken by these coupled modes are discussed for the general case and for special cases of symmetry; the forms are illustrated by

New Insight into Interaction of Buckling Modes with Stable Post-buckling Response

Arabian Journal for Science and Engineering, 2014
Buckling mode interaction of elastic systems in the presence of initial imperfections is well known to have a detrimental effect on the response of a wide range of structural systems. This has been demonstrated mostly analytically for simple models, assuming small displacements, thus obtaining results with questionable validity in the post-buckling ...

Buckling mode as an imperfection in arch structures

Pollack Periodica, 2013
An Equivalent Unique Global and Local Imperfection (sometimes referred as an ‘EUGLI’ imperfection) is an equivalent imperfection that has a shape affine to the form of a critical elastic buckling mode. This design method, in its generalized form designated for the frame structures, is included in the EN 1993-1-1 cl. 5.3.2 (11) since 2002.

On seeking buckling modes of a circular plate

Journal of Applied Mathematics and Mechanics, 1990
The paper deals with the buckling of a circular plate with constant thickness and axisymmetric deformation. The nonlinear Kármán equations are used for solving the problem. The solution is obtained by using series in Bessel functions. The differential equations are transformed into an infinite system of nonlinear algebraic equations.

High‐mode buckling responses of buckling‐restrained brace core plates

Earthquake Engineering & Structural Dynamics, 2013
SUMMARYCyclic loading tests and finite element analyses on six novel all‐steel buckling‐restrained braces (BRBs) are conducted using different loading patterns to investigate the core plate high‐mode buckling phenomenon. The proposed BRB is composed of a core member and a pair of identical restraining members, which restrains the core member by using ...

FINITE ELEMENTS FOR THREE-MODE INTERACTION IN BUCKLING ANALYSIS

International Journal for Numerical Methods in Engineering, 1996
This paper presents a finite element formulation for the buckling mode interaction analysis of structures modelled as plate assemblies. The main assumptions are linear elasticity, a linear fundamental path, the existence of distinct critical states that are coincident or near coincident, and a coupled path arising from a linear combination of modal ...

Dynamic buckling mode of an elastic bar

Applied Mathematics and Mechanics, 1990
The conception of buckling relative initial imperfection is presented in this paper. According to Boulli-Euler beam equation, the dynamic buckling mode of an elastic bar under the homogeneous boundary conditions can be derived by applying the preferred mode analytical method.
