Postbuckling Behavior of Composite Shear Webs

AIAA Journal, 1980
In this paper the postbuckling behavior of multibay composite shear webs is explored. Several test specimens are designed through the use of advanced state of the art design methods taking into account material anisotropy. The panels are subjected to static as well as fatigue loading in a series of well instrumented and carefully conducted tests to ...

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.

Postbuckling behavior of a thick plate

AIAA Journal, 1983
The postbuckling behavior of a simply supported rectangular thick plate subjected to arbitrary loading conditions is investigated. The applied stress is taken to be a combination of a pure bending stress plus an extensional stress in the plane of the plate.

Buckling and postbuckling of composite structures

Composites, 1995
Abstract The postbuckling behaviour of a flat, stiffened, carbon fibre composite compression panel has been studied, theoretically and experimentally. The panel had a collapse load in excess of three times the buckling load. An initial failure mechanism leading to eventual explosive collapse of the panel is identified and the damaging stress ...

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

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 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

Buckling and Postbuckling of Orthotropic Plates

AIAA Journal, 1976
Theme T stability is considered of flat rectangular plates when in-plane biaxial loads are applied. The in-plane and bending elastic properties are orthotropic and the plate axes of symmetry and the elastic axes of symmetry coincide. Both the initial buckling and the reduction in stiffness occurring at the instant of buckling are considered.
