Stability of thin-walled tubes under torsion

Stability of thin-walled tubes under torsion

Date: January 1, 1935
Creator: Donnell, L H
Description: In this report a theoretical solution is developed for the torsion on a round thin-walled tube for which the walls become unstable. The results of this theory are given by a few simple formulas and curves which cover all cases. The differential equations of equilibrium are derived in a simpler form than previously found, it being shown that many items can be neglected.

Stability of Tube Rows in Crossflow

Stability of Tube Rows in Crossflow

Date: October 1982
Creator: Chen, S. S. & Jendrzejczyk, J. A.
Description: A mathematical model for the instability of tube rows subjected to crossflow is examined. The theoretical model, based on the fluid-force data for a pitch-to-diameter ratio of 1.33, provides additional insight into the instability phenomenon. Tests are also conducted for three sets of tube rows. The effects of mass ratio, tube pitch, damping, detuning and finned tubes are investigated. Theoretical results and experimental data are in good agreement.

Stability of Tubes Conveying Fluid

Stability of Tubes Conveying Fluid

Date: April 1984
Creator: Chen, Shoei-Sheng & Jendrzejczyk, J. A.
Description: Tests and analysis are made for tubes conveying fluid for two types of support conditions. The objectives are to study the characteristics of different types of instability, the transition of one instability mechanism to another, and the control of instability.
