Nonlinear buckled states of rectangular plates

Archive for Rational Mechanics and Analysis, 1974
A constructive method is developed to establish the existence of buckled states of a thin, flat elastic plate that is rectangular in shape, simply supported along its edges, and subjected to a constant compressive thrust applied normal to its two short edges.

Nonlinear buckling of cylindrical shells

Computers & Structures, 1972
A method is presented for the study of the nonlinear buckling of shallow cylindrical shells. The governing differential equations are expressed in terms of a stress function and the normal displacement. The Kantorovitch method and a finite difference scheme are applied to solve the resulting set of nonlinear differential equations.

Nonlinear buckling of blood vessels: A theoretical study

Journal of Biomechanics, 2008
Tortuosity and kinking often occur in arteries and veins but the underlying mechanisms are poorly understood. It has been suggested recently that long arteries may buckle and become tortuosity due to reduced axial tension or hypertensive pressure, but very few studies have been done to establish the biomechanical basis for artery buckling.

In-Plane Nonlinear Buckling of Funicular Arches

International Journal of Structural Stability and Dynamics, 2015
This paper presents a numerical technique to determine the full pre-buckling and post-buckling equilibrium path for elastic funicular arches. The formulation includes the effects of shear deformations and geometric nonlinearity due to large deformations. The Timoshenko beam hypothesis is adopted for incorporating shear.

Nonlinear Dynamic Buckling of a Composite Shell

46th AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics and Materials Conference, 2005
A computationally effective method is described to evaluate the nonlinear dynamic buckling of thin composite shells. The method is a judicious combination of available computer codes for finite element, composite mechanics and incremental structural analysis. The solution method is an incrementally updated Lagrangian.

A Model for the Nonlinear Buckling of Human Aorta

Volume 4: Dynamics, Control and Uncertainty, Parts A and B, 2012
Human aortas are subjected to large mechanical stresses due to blood flow pressurization and through contact with the surrounding tissue. It is essential that the aorta does not lose stability by buckling for its proper functioning to ensure proper blood flow. A refined reduced-order bifurcation analysis model is employed to examine the stability of an

Nonlinear Buckling Analysis of Sandwich Arches

Journal of the Engineering Mechanics Division, 1971
An incremental displacement formulation for the nonlinear finite element analysis of sandwich arches is presented. The formulation permits the analysis of geometrically nonlinear problems with finite rotations but infinitesimal strains. The finite element model employed is a straight beam-column type, and has a three-layered sandwich construction with ...

Nonlinear Interactive Buckling: Sensitivity and Optimality∗

Journal of Structural Mechanics, 1977
ABSTRACT The nonlinear buckling behavior of discrete systems in which two eigen-modes interact is studied. A variable parameter affecting the design is introduced to allow a change in the closeness of the two eigenvalues. The sensitivity of the critical equilibrium states to combined changes in the design and imperfection parameters is considered ...
