Effects of constraint curvature on structural instability: tensile buckling and multiple bifurcations [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2012 Bifurcation of an elastic structure crucially depends on the curvature of the constraints against which the ends of the structure are prescribed to move, an effect which deserves more attention than it has received so far.

Bifurcation analysis and phase diagram of a spin-string model with buckled states [PDF]
Physical Review E, 2017 We analyze a one-dimensional spin-string model, in which string oscillators are linearly coupled to their two nearest neighbors and to Ising spins representing internal degrees of freedom.

Double-eigenvalue bifurcation and multistability in serpentine strips with tunable buckling behaviors [PDF]
Journal of the Mechanics and Physics of SolidsSerpentine structures, composed of straight and circular strips, have garnered significant attention as potential designs for flexible electronics due to their remarkable stretchability. When subjected to stretching, these serpentine strips buckle out of plane, and previous studies have identified two distinct buckling modes whose order of appearance ...

Bifurcation Buckling Analysis and Non-Linear Collapse Analysis of Teardrop Shaped Vacuum Chamber
Volume 2: Computer Technology and Bolted Joints; Design and Analysis, 2022 The Spallation Neutron Source (SNS) accelerator is being upgraded to increase the beam power from 1.4MW at 1GeV to 2.8MW at 1.3GeV. The currents in the middle two injection chicane magnets cannot simply be scaled up to accommodate the increased ...

Geometrically exact bifurcation and post-buckling analysis of the granular elastica
International Journal of Non-Linear Mechanics, 2021 Abstract The nonlinear behaviour of a simply supported granular column loaded by an axial force is studied in this paper. The granular column is composed of rigid grains (discs) elastically connected by some shear and rotational springs. The in-plane buckling and post-buckling analysis in a geometrically exact framework is numerically investigated ...

Analytical Displacement-Controlled Solutions to Bifurcation Buckling and Post-Buckling of Soft Functional Beams with Constrained Ends [PDF]
, 2023 Abstract The soft functional beams in many modern devices usually have elastic bifurcation buckling under the end-displacement control, which is essential to their consequent functions. The concise and accurate analytical solutions for the buckling and post-buckling analysis are needed to fast design these beams. Here we derive some closed-form

Instability by Extension of an Elastic Nanorod [PDF]
NanomaterialsThe static stability of an elastic, incompressible nanorod subjected to an extensional force is analyzed. The force is applied to a rigid rod that is welded to the free end of the nanorod.

Design space for bifurcation buckling of laser-welded web-core sandwich plates as predicted by classical and micropolar plate theories [PDF]
Annals of Solid and Structural Mechanics, 2020 The strength of laser-welded web-core sandwich plates is often limited by buckling. In design of complex thin-walled structures the combination of possible structural and material combinations is basically infinite.
