Finite Element Buckling and Postbuckling Analyses

Buckling and Postbuckling of Composite Structures, 1994
Abstract An overview is given of the finite element buckling and postbuckling analyses of composite plates. Discussion focuses on finite element formulations of the prebuckling, bifurcation buckling and postbuckling responses; sensitivity analysis; application of reduction methods and otherrecent computational enhancements.

Postbuckling Analysis of a Magnetoelastic Beam

Journal of Applied Mechanics, 1972
The initial postbuckling behavior of an elastic ferromagnetic beam in a transverse magnetic field is studied. The cantilever beam is found to be imperfection-sensitive. Imperfections due to deviations from straightness of the beam and due to misalignment of the field with the normal to the beam are investigated.

Studies of Postbuckled Shapes

2020
The previous chapter considered the initiation of instabilities; we conclude this book with an introduction to postbuckled shapes. Postbuckling behavior is a large deformation problem initiated by a singularity and this singularity helps delineate between the pre- and post-phases.

Elastic postbuckling with nonlinear constraints

International Journal of Solids and Structures, 1996
Abstract Koiter’s asymptotic theory of initial postbuckling and imperfection sensitivity of elastic structures is expanded such that almost any auxiliary condition can be handled directly. The theory, which employs Lagrange multiplier techniques , is valid for strain measures that are quadratic in the displacements, i.e. it is exact for Lagrangian

Postbuckling Behavior of Thin Cylinders

Journal of the Engineering Mechanics Division, 1968
Results of 550 axial load tests on 47 thin cylinders made of Mylar are presented. The experiments show that the number of circumferential buckling waves, \IN\N, is a function of \IL/R\N in addition to its established dependency on \IR/t\N. An approximate relation for \IN\N is derived. Also, it is demonstrated that thin cylinders under axial load buckle

Postbuckling analysis using a general-purpose code

AIAA Journal, 1985
A new capability for solving postbuckling problems in shell structures is described. The matrix theory to adapt Newton's method to nonlinear finite element shell analysis is outlined first. The matrix theory is directed at writing consistent linear algebratic equations for problems where the tangent stiffness matrix is singular or nearly singular.

Postbuckling Failure of Composite Panels

1985
A series of postbuckling tests have been conducted on thin rectangular quasi-isotropic CFRP panels. The testing machine allowed careful control of panel loading and by using acoustic emission as a diagnosis it was possible to monitor the onset and progress of failure before compression collapse destroyed the evidence.
