Plastic Bifurcation Buckling of Toroidal Shells

Journal of the Engineering Mechanics Division, 1979
The buckling characteristics of shells with double curvature is an important design consideration of such structures. Aircraft structural components are commonly of the double curvature type. Classical elastic buckling of toroidal shell segments with positive and negative Gaussian curvatures under pressure loading is given by Stein and McElmann.

Bifurcation buckling from a membrane stress state

International Journal for Numerical Methods in Engineering, 2012
SUMMARYA membrane stress state may be considered as a general stress state in which mechanical constraints have been imposed. Therefore, it would appear that there are mathematical subsidiary conditions for bifurcation buckling from such a stress state. In this work, such conditions are derived in the frame of the Finite Element Method.

Analysis of post‐buckling branches at multiple symmetric bifurcations

International Journal for Numerical Methods in Engineering, 2001
AbstractA method to analyse and solve symmetric bifurcations by establishing the bifurcation equations using an asymptotic expansion method is presented. The bifurcation equations are obtained using a decomposition of the spaces by means of the theory of Lyapunov–Schmidt. To solve the bifurcation equations an asymptotic expansion method along the lines

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

Singular global bifurcation problems for the buckling of anisotropic plates

Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences, 1990
Abstract This paper treats a variety of unexpected pathologies that arise in the global bifurcation analysis of axisymmetrie buckled states of anisotropic plates. The geometrically exact plate theory used accounts for flexure, extension and shear. The nonlinear constitutive functions have very general form.

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 ...
