Oscillatory Buckling Mode in Thin-Film Nucleation
Journal of Nonlinear Science, 2006We are interested in switching of elongated thin-film elements as described by the micromagnetic model. Nucleation occurs when the saturation branch becomes unstable at a critical field. It is characterized by a degeneracy of the Hessian of the micromagnetic energy. The degenerate subspace describes the unstable mode.

Buckling Mode Interaction in Composite Plate Assemblies
Applied Mechanics Reviews, 1995The analysis of buckling mode interaction of fiber-reinforced composite columns, modeled as plate assemblies, is presented. The main assumptions are linear elasticity; a linear fundamental equilibrium path; the existence of critical states that are coincident or near coincident; and a coupled path rising from a quadratic combination of modal ...

AIAA Journal
This study presents novel accurate nonlinear buckling solutions of ring-stiffened cylindrical shells. A theoretical model based on the discrete stiffener theory for nonlinear buckling is first developed, which can account for multiple buckling modes, including overall buckling, local buckling, coupled buckling, and tripping.

Buckling mode localization in multi-span columns
35th Structures, Structural Dynamics, and Materials Conference, 1994The mode-localization phenomenon is utilized in order to passively control structural buckling. An exact treatment is presented for the buckling problem of a multi-span column that involves certain irregularities, including intermediate torsional springs and/or displaced intermediate supports.

Chessboard-like buckling modes of compressed materials
Doklady Physics, 2012A transversally isotropic uniform elastic medium is considered during uniform compression in the isotropy plane. Under definite assumptions on the elasticity moduli of the material, it is established that the buckling mode during the postcritical compression has a stable chessboard-like character.

Elastic Buckling with Infinitely Many Local Modes
Mechanics of Structures and Machines, 1987ABSTRACT ABSTRACT In some cases, asymptotic methods present an appealing alternative to full nonlinear analyses. In other cases, the value of an asymptotic analysis may merely be that, in a qualitative way, it can characterize the behavior of a structure.

Buckling mode shapes of thin-walled members
Computers & Structures, 1995Summary: An analytical procedure to estimate not only the elastic buckling loads but also buckling mode shapes by transfer matrix method is presented. The transfer matrix is derived from the differential equations for the plate subjected to axial load.

FINITE ELEMENTS FOR THREE-MODE INTERACTION IN BUCKLING ANALYSIS
International Journal for Numerical Methods in Engineering, 1996This 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 ...
