Equilibrium equations for 3D critical buckling of helical springs

Applied Mathematics and Mechanics, 2012
In most cases, the research on the buckling of a helical spring is based on the column, the spring is equivalent to the column, and the torsion around the axial line is ignored. A three-dimensional (3D) helical spring model is considered in this paper.

Onset and Post Buckling of Pipe-in-Pipe’s Helical Buckling Using Improved Energy Method

Volume 3: Structures, Safety, and Reliability, 2018
The purpose of this paper is to present theoretical solutions based on an improved energy method for predicting the helical buckling (HB) behavior of pipes in vertical, inclined, and horizontal wells. The energy method has been applied to solve the pipe-in-pipe’s (PIP) helical buckling behavior since Lubinski, et al [2] in the 1950’s ...

New Analytic Solutions for Pipe Helical Buckling Problems

Proceedings of International Oil and Gas Conference and Exhibition in China, 2010
Abstract There are some numerical solutions(4,5) for pipe buckling problems in vertical and horizontal wells, but, we need exact analytic solutions for precise analysis of pipe buckling problems. The first analytic solution for pipe buckling in a vertical well was presented by Lubinski and Woods in 1962(2).
