Prediction of Helical / Sinusoidal Buckling

SPE/IADC Asia Pacific Drilling Technology, 1996
Abstract A set of equations for helical and sinusoidal buckling under an ideal condition, where weight and frictional effects are not considered have been derived based on experimental and FEA data. An experimental method was developed canceling out frictional effects and FEA was carried out independently on both ...

Sinusoidal buckling behaviour of surface casing with negative friction in thawing permafrost

Journal of Petroleum Science and Engineering, 2022
Abstract During the development of oil fields in permafrost regions, once the surface casing buckling occurs under the formation thawing and subsidence, it will cause great economic losses. In this paper, sinusoidal buckling of surface casing under negative friction is studied and preliminarily discussed.

Sinusoidal phase grating created by a tunably buckled surface

Applied Physics Letters, 2004
We investigate a buckling instability by both small angle light scattering and atomic force microscopy, demonstrating that a tunable phase grating can be created with a mechanical instability. The instability is realized in a prestressed silicone sheet coated with a glassy polymer film.

Effect of sinusoidal and inverse sinusoidal In-plane loads on buckling and vibration characteristics of FRP panels with cutouts

Materials Today: Proceedings, 2021
Abstract The cutouts usually observed inside the aircraft and ship constructions toward facilitating water tubes, oil pipelines, electrical ducts, doorways, portholes and sometimes inspection objectives. These cutouts severely alter the vibration and buckling properties of the structural components.

Experimental and Analytical Study of Sinusoidal Buckling in Vertical Wells

Proceedings of SPE Eastern Regional Meeting, 1994
ABSTRACT This paper presents results from experimental data for sinusoidal buckling of tubulars in vertical wells and discusses some analytical solutions presented in the literature. An experimental apparatus 55 feet long was used in the tests. Several tests have been conducted and the results are presented and analyzed.

Elastic shear buckling of sinusoidally corrugated steel plate shear wall

Engineering Structures, 2016
Abstract This paper deals with elastic shear buckling behavior of infill panels in sinusoidally corrugated steel plate shear walls, and fitting equations predicting the shear buckling loads are presented. Firstly by using finite element analyses (FEA), the previous formulae for bending rigidities of sinusoidally corrugated plates are revised, then ...
