MODE JUMPING AND ATTRACTIVE PATHS IN MULTIMODE ELASTIC BUCKLING
International Journal for Numerical Methods in Engineering, 1997Summary: This paper examines multimode elastic buckling within an FEM strategy. The theoretical arguments unfold among critical points on radial paths (the unique post-critical path variationally defined), algebraic characterizations, and so on, by aiming to prove that the complexity of the phenomenon of multimode buckling (secondary bifurcations, post-

The electromechanical response of silicon nanowires to buckling mode transitions
Nanotechnology, 2010Here we show how the electromechanical properties of silicon nanowires (NWs) are modified when they are subjected to extreme mechanical deformations (buckling and buckling mode transitions), such as those appearing in flexible devices. Flexible devices are prone to frequent dynamic stress variations, especially buckling, while the small size of NWs ...

Two Distinct Buckling Modes in Carbon Nanotube Bending
Nano Letters, 2006By using controlled SPM manipulation, carbon nanotubes have been continuously bent into a series of increasing angles, and two distinct buckling modes corresponding to "abrupt" and "gradual" buckle formation were observed through recording the height increment at the bend site during the loading process. Molecular dynamics simulation also found the two

Buckling Analysis of Tapered Continuous Columns by Using Modified Buckling Mode Shapes
Journal of Marine Science and Application, 2019Elastic critical buckling load of a column depends on various parameters, such as boundary conditions, material, and cross-section geometry. The main purpose of this work is to present a new method for investigating the buckling load of tapered columns subjected to axial force.

Initial Postbuckling With a Unique Buckling Mode
2013Here, we consider problems that belong to the category of Chap. 18, namely problems with Linear Prebuckling, but take a broader view in that we establish a procedure for investigating the initial behavior after buckling—the Postbuckling Behavior.

Buckling-Mode Number and Compressive-to-Tensile Strength Ratio of Buckling-Restrained Braces
2014Buckling-restrained braces (BRBs) are composed of a steel core, which resists axial force, and a buckling-restraining system. A carefully designed clearance, often filled with unbonding material, is placed between the steel core and restraining system to avoid force transfer between the two components.

Koiter's Buckling Mode for Short Cylindrical Shells
AIAA Journal, 1972All working equations (except the assumed deflections) are derived from operations performed on the energy functional, that is, the summation of all the quadratic energy terms associated with the deformation during buckling, as developed by Koiter. This is given in Ref. 1 and has been modified in Ref.

BUCKLING LOAD AND POST-BUCKLING SOLUTION FOR MODE SHAPE OF DELAMINATED BEAM
2012This paper presents elastic buckling and post-buckling analysis of an axially loaded isotropic beam-plate with an across-the- width delamination located at a given depth, subjected to in-plane compression. A simple analytical model for determining the global buckling load of the plate with delamination and the mode shape is developed, for various ...
