Normal menisci may show transient distortion during knee arthrography. This usually results from intermittent visualization of the meniscus out of direct profile to the x-ray beam. Similar transient distortion may result from actual buckling of an anatomically normal meniscus during stressful maneuvers in young individuals.

Buckling and Post-buckling of Beams
2017This chapter presents buckling and post-buckling analysis of straight beams under thermal and mechanical loads. The Euler and Timoshenko beam theories are considered and buckling and postbuckling behaviors are discussed. The buckling analysis of beams with piezoelectric layers is presented and the effect of piezo-control on the beam stability is ...

Objectives: In this chapter we analyse the stability of equilibrium positions of bars under compressive loads. Methods are presented which will enable us to determine the so-called critical load under which a bar deflects due to buckling. The aim is to enable students to apply the appropriate methods in order to determine critical loads.

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.

Thermal buckling analysis of SWBNNT on Winkler foundation by non local FSDT
, 2019In this work, the thermal buckling characteristics of zigzag single-walled boron nitride (SWBNNT) embedded in a one-parameter elastic medium modeled as Winkler-type foundation are investigated using a nonlocal first-order shear deformation theory (NFSDT).

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.
