The Effects of Boundary Conditions and Friction on the Helical Buckling of Coiled Tubing in an Inclined Wellbore. [PDF]

PLoS ONE, 2016
Analytical buckling models are important for down-hole operations to ensure the structural integrity of the drill string. A literature survey shows that most published analytical buckling models do not address the effects of inclination angle, boundary ...

Study on helical post-buckling of motional coiled tubing in horizontal wells

Journal of Petroleum Exploration and Production Technology
Coiled tubing is widely used in oil and gas operations. However, the long coiled tubing may undergo sinusoidal or helical buckling deformations, and even lock-up, leading to property damage and serious accidents.

Plastic buckling of initially imperfect stiffened cylinders in axial compression [PDF]

, 1981
Bibliography: leaves 117-118.Bifurcation in the plastic range of axially compressed stringer-stiffened cylinders is investigated. The shell under consideration is assumed to have an initial imperfection in the form of a sinusoidal deviation both axially ...
