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.

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 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.

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.

Local buckling analysis of periodic sinusoidal corrugated composite panels under uniaxial compression

Composite Structures, 2019
Abstract The critical local buckling of simply-supported sinusoidal panels subjected to uniaxial compression using the Rayleigh-Ritz method is investigated. With increased applications of thin-walled composite structures in engineering, these corrugated panels are especially popular due to their high stiffness to weight ratio and high out ...
