Bifurcation Criterion and Plastic Buckling of Plates and Columns

Journal of the Aeronautical Sciences, 1950
If a bifurcation of equilibrium paths occurs as the loading is varied on a conservative system, the preferred path is usually obtained by use of a stability criterion. However, even if the definition of stability is modified so as no longer to depend on the existence of a potential energy function, a stability criterion may not be useful if the system ...

Homoclinic Bifurcation and Localised Torsional Buckling of Elastic Rods

1997
In this paper we study localised buckling in elastic rods with non-symmetric crosssection, which has applications in undersea cable and drillstring buckling as well as in DNA engineering [10]. Strong evidence will be given of the existence of an infinity of localised buckling modes.

Periodic Motions and Bifurcation Trees in a Buckled, Nonlinear Jeffcott Rotor System

International Journal of Bifurcation and Chaos, 2015
In this paper, analytical solutions for period-m motions in a buckled, nonlinear Jeffcott rotor system are obtained. This nonlinear Jeffcott rotor system with two-degrees of freedom is excited periodically from the rotor eccentricity. The analytical solutions of period-m solutions are developed, and the corresponding stability and bifurcation are also

Bifurcation, limit-point buckling, and dynamic collapse of transversely loaded composite shells

AIAA Journal, 2000
The transverse-loading response of laminated composite shell structures is studied experimentally and numerically. Monolithic graphite/epoxy shell structures having layups of [§ 45n/0n]s (n= 1;2;and3) closely represent commercial fuselage structures in both geometry and boundary conditions.

Nonlocal nonlinear static/dynamic snap-through buckling and vibration of thermally post-buckled imperfect functionally graded circular nanoplates

Waves in Random and Complex Media, 2022
The bi-stability characteristics of the post-buckled plates have demonstrated extensive potential applications for energy harvesting and vibration isolation.

Stability, Bifurcation and Postbuckling Analysis

1998
Liapunov theory is first presented and discrete mechanical systems are in particular analysed. Then buckling and postbuckling analysis of continuous mechanical systems due to Koiter are discussed in some detail following Budiansky presentation. Finally, the influence of multiple interactive buckling modes on postbuckling behaviour is analysed in some ...

Post-buckling bifurcations and stability of high-speed axially moving beams

International Journal of Mechanical Sciences, 2013
Abstract The nonlinear forced dynamics of an axially moving beam in the supercritical speed regime is numerically investigated in this paper, with special consideration to the case possessing an internal resonance between the first two modes. At critical speed, the initial equilibrium configuration of the beam becomes unstable and a new stable non ...
