An experimental and numerical study on inward integral buckle arrestors for pipe-in-pipe systems

Ships and Offshore Structures, 2018
A type of improved device, designated as inward integral buckle arrestor, is introduced for the pipe-in-pipe (PIP) systems. The experiments have been performed to reproduce the buckle propagation and crossover scenarios of the PIP installed with such ...

Buckling and Post-Buckling of Spherical Caps

Journal of the Engineering Mechanics Division, 1971
The results of a numerical study of the buckling and initial post-buckling behavior of clamped shallow spherical shells under axisymmetric band type loads are presented. This behavior is studied, first, for a cap with fixed geometry when the radial location of a band load of constant width is allowed to vary; second, for a cap with fixed geometry under

Buckling and post-buckling of graphene tubes

Mechanics of Advanced Materials and Structures, 2015
AbstractBuckling and post-buckling of a long, thin, inextensible tube made of graphene material acted upon by a uniform normal pressure are considered. A system of differential equations governing the equilibrium states of such a tube is derived.

Buckling and post-buckling of beams with flat webs

Thin-Walled Structures, 2005
Post-buckling of a stiffener beam subjected to single shear load was experimentally investigated. The results were analysed using Wagner theory and non-linear finite elements. A new method was proposed to study the postbuckling behaviour. Each panel is divided into two zones.

Membrane Buckling Patterns and Secondary Buckling Analysis [PDF]

International Journal of Space Structures, 2008
In 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.

FLEXURAL-SLIP DURING VISCO-ELASTIC BUCKLE FOLDING

, 2017
Flexural-slip is considered as an important mechanism during folding and a general conceptual and qualitative understanding has been provided by various field studies. However, quantitative evidence of the importance of the flexural-slip mechanism during

Self-Buckling at the Nanoscale

Advances in Science and Technology, 2010
In this paper the self-buckling of nanostructures, such as nanotubes, fullerenes and peapods, is analytically treated; this surprising phenomenon is due to the interaction among the nanostructures caused by the surface energy; it is peculiar of the nanoscale and has not a macroscopic counterpart.

Buckled Meniscus

Radiology, 1978
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

2017
This 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 ...

Buckling of Bars

2011
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.
