Geometric Analysis of Radial Buckling
American Journal of Ophthalmology, 1975Tension analysis along the retinal surface demonstrates the advantage of meridional buckles over limbal-parallel buckles. A cylindrical sponge generates tensional forces in the retina along the long axis of the buckle and perpendicular to it. The tension perpendicular to the sponge is positive, and the retina and retinal pigment epithelium stretch in ...

Membrane Buckling Patterns and Secondary Buckling Analysis
International Journal of Space Structures, 2008In this paper, the shear wrinkles of a rectangular membrane under the pretension were analyzed firstly. A critical shear distance was then obtained based on the tension field theory. An expression between the wavelength and the amplitude of the membrane wrinkles were developed using the Von Karman large deflection formula.

Numerical analysis and experimental correlation of composite shell buckling and post-buckling
Composites Part B: Engineering, 2000Abstract This paper deals with the buckling and post-buckling behaviour of carbon fibre reinforced plastic cylindrical shells under axial compression. The finite element analysis is used to investigate this problem and three different types of analysis are compared: eigenvalue analysis, non-linear Riks method and dynamic analysis.

Polymer Engineering & Science, 1972
AbstractThis paper presents results obtained by the experimental technique of photoelastic stress analysis and by finite or discrete element analysis, applied to the case of buckling of a single, axially‐loaded metal fiber embedded in a plastic matrix. The program was conducted utilizing a mild steel fiber embedded in an epoxy resin system.

Elastoplastic buckling and post-buckling analysis of sandwich columns
International Journal of Non-Linear Mechanics, 2015Abstract Sandwich structures are widely used in many industrial applications thanks to their interesting compromise between lightweight and high mechanical properties. This compromise is realized thanks to the presence of different parts in the composite material, namely the skins which are particularly thin and stiff relative to the homogeneous core

Summary A new solution to helical buckling is presented yielding real helical shapes of buckled pipes with a varying helix pitch. This solution has been developed with the beam/column equation. The change in length and the bending stress can be computed from the helical-buckling solution. In addition, a new equation for tool clearance in

Buckled Elastica at Contact: A Perturbation Analysis
SIAM Journal on Applied Mathematics, 1979The postbuckling shape of a slender elastic rod clamped at both ends and subject to an axial compressive force is considered. The critical value \(P_c\) of the magnitude of the axial force is assumed to cause the rod to bend so far out as to come into contact with itself for the case of the first buckling mode.

Linear Buckle Analysis for Partially Buckled Webs
Computational Methods for Solution of Inverse Problems in Mechanics, 1998Abstract Web processing requires that the web is stretched under tension between two processing rolls. When the processing rolls are misaligned or moved relative to each other, a web deflection is introduced which causes the web stress to change. Small roll misalignments or movements may cause large web stresses, yielding, and failure.

On the analysis of viscoplastic buckling
International Journal of Solids and Structures, 1993Abstract For elastic-viscoplastic structures the classical elastic-plastic bifurcation approach to inelastic buckling is not valid. Only an elastic bifurcation point exists in the elastic-viscoplastic case, and the inelastic buckling behaviour is controlled by a strong sensitivity to small imperfections.
