Sinusoidal buckling of a thin rod with connectors constrained in a cylinder

Journal of Natural Gas Science and Engineering, 2014
Abstract Kinds of tubular strings with connectors are widely used in petroleum exploration and development field. In previous research, tubular strings are usually treated as homogeneous thin elastic rods constrained in a cylinder and few studies have been made on the effect of connectors.

Sinusoidal buckling of a thin rod with connectors constrained in a torus

Journal of Natural Gas Science and Engineering, 2014
Abstract Kinds of tubular string are widely used in oil exploration and development. These tubular strings are usually approximately seen as homogeneous thin elastic rods without connectors constrained in a straight cylinder or torus. Recent research has shown that connectors play an important role on rod deflection problem.

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.

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.

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 ...
