The secondary buckling transition: Wrinkling of buckled spherical shells [PDF]
The European Physical Journal E, 2014 We theoretically explain the complete sequence of shapes of deflated spherical shells. Decreasing the volume, the shell remains spherical initially, then undergoes the classical buckling instability, where an axisymmetric dimple appears, and, finally, loses its axisymmetry by wrinkles developing in the vicinity of the dimple edge in a secondary ...

Pneumatic retinopexy versus scleral buckle for repairing simple rhegmatogenous retinal detachments.
Cochrane Database of Systematic Reviews, 2015 BACKGROUND Rhegmatogenous retinal detachment (RRD) is a full-thickness break in the sensory retina, caused by vitreous traction on the retina. While pneumatic retinopexy, scleral buckle, and vitrectomy are the accepted surgical interventions for eyes ...

Buckling of Liquid Columns [PDF]
Physical Review Letters, 2010 Under appropriate conditions, a column of viscous liquid falling onto a rigid surface undergoes a buckling instability. Here we show experimentally and theoretically that liquid buckling exhibits a hitherto unsuspected complexity involving three different modes-viscous, gravitational, and inertial-depending on how the viscous forces that resist bending

Physical Review Letters, 2017 We investigate the mechanical response of thin sheets perforated with a square array of mutually orthogonal cuts, which leaves a network of squares connected by small ligaments. Our combined analytical, experimental and numerical results indicate that under uniaxial tension the ligaments buckle out-of-plane, inducing the formation of 3D patterns whose ...

Computer Methods in Applied Mechanics and Engineering, 2016 Abstract The basis of this work is a novel symbiosis of mechanics of solids and spherical geometry to quantify and illustrate the variation of the “non-membrane” percentage of the strain energy in the prebuckling region of linear elastic beams, arches, plates and shells, and structures assembled of such one-dimensional and two-dimensional members ...

Buckling of a holey column [PDF]
Soft Matter, 2016 Introducing holes within an elastic column provokes a novel buckling mode (centre) occuping less space than conventional lateral buckling.

Bibliography of research using the NZIER’s quarterly survey of business opinion [PDF]
, 2011 The New Zealand Institute of Economic Research (NZIER) has conducted and published a quarterly survey of business opinion continuously, and with largely unchanged questions, since June 1961.

Buckle fractures of the distal radius in children
Canadian Medical Association Journal, 2016 Buckle (torus) fractures occur when the bony cortex is compressed and bulges, without extension of the fracture into the cortex ([Figure 1][1]). This type of fracture occurs in about 1 in 25 children and represents 50% of pediatric fractures of the wrist.

Physical Review Letters, 2012 A scroll wave in a sufficiently thin layer of an excitable medium with negative filament tension can be stable nevertheless due to filament rigidity. Above a certain critical thickness of the medium, such scroll wave will have a tendency to deform into a buckled, precessing state. Experimentally this will be seen as meandering of the spiral wave on the

Buckling Bars and Boxy Bulges [PDF]
, 1995 It has been suggested that the peanut-shaped bulges seen in some edge-on disk galaxies are produced when bars in these galaxies buckle. This paper reviews the modelling which seeks to show how bars buckle, and I present a very simple new model which ...
