Buckling and post-buckling of annular plates in shearing, Part I: Buckling
Computer Methods in Applied Mechanics and Engineering, 1991Abstract Using the generalized and modified Von Karman theory for perforated thin plates having large deflections, the elastic buckling of annular plates under in-plane shear forces is studied in this paper. The mathematics problem is formulated rationally.

In many examples in the preceding chapters we have seen that shells can be very thin-walled and that they very often are subjected to compressive stresses in extensive areas. The question arises whether the elastic equilibrium of such shells is stable.

Buckling instabilities in cholesterics
Journal of Applied Physics, 1982Quantitative measurements on the threshold of mechanically induced buckling instabilities are presented. We report the data obtained by light scattering experiments, and by optical spectroscopy measurements. We verify de Gennes’ model for this instability qunatitatively, in analogy with the smectic A case, obtaining an equivalent penetration length of ...

Thermoelastic buckling and post-buckling of weakened columns
Structures, 2015Abstract Structural columns in engineering practice may weaken over time as a result of corrosion, erosion, impact, fatigue cracking or similar effects that reduce their effective cross-section. The effect of the degradation of the cross-section may then lead to premature flexural buckling.

In this paper, a numerical study of the dynamic buckle propagation, initiated in long pipes under external pressure, is presented. For a long pipe, due to the high exerted pressure, local instability is likely to occur; therefore, the prevention of its ...

Buckling and post-buckling of laminated composite plates
Mechanics Research Communications, 2012Abstract This paper addresses the buckling and post-buckling of laminated composite plates using higher order shear deformation theory associated with Green–Lagrange non-linear strain–displacement relationships. All higher order terms arising from nonlinear strain–displacement relations are included in the formulation.

To evaluate the feasibility of suprachoroidal buckling procedure using a suprachoroidal catheter, or cannula, as a new approach to treating different forms of retinal detachment, including myopic traction maculopathy, myopic macular holes, and peripheral retinal breaks by creating a suprachoroidal indentation (buckling effect) using a suprachoroidal ...

Cryotherapy vs laser photocoagulation in scleral buckle surgery: A randomized clinical trial.
A M A Archives of Ophthalmology, 2010OBJECTIVE To compare the reattachment rate and visual acuity results among patients with rhegmatogenous retinal detachment who underwent scleral buckle surgery with retinopexy by intraoperative cryotherapy (cryopexy) vs postoperative (1 month later ...

Torsional-flexural buckling of locally buckled columns
Computers & Structures, 1980Abstract An investigation dealing with the interaction of local and overall buckling of thin-walled columns is described. Due to weakening effects of local buckling, overall buckling (flexural, torsional, or torsionalflexural) takes place at a lower load than the column would carry in the absence of local buckling.

Buckling and Post-buckling Behaviour of Plates with Holes
Aeronautical Quarterly, 1975SummaryThis paper gives details of theoretical and experimental investigations into the behaviour of simply-supported uniformly compressed square and rectangular plates with central circular holes. The theoretical analysis employs an approximate approach using a combination of Rayleigh-Ritz and finite-element methods.
