Collapse of Sharp-Notched 6061-T6 Aluminum Alloy Tubes Under Cyclic Bending
TL;DR: In this article, the authors investigated the behavior and buckling failure of sharp-notched 6061-T6 aluminum alloy tubes with different notch depths subjected to cyclic bending and proposed a theoretical model for simulation of the controlled curvature-number of cycles concerning the initiation of buckling.

On the collapse of inelastic tubes under combined bending and pressure
TL;DR: In this paper, the response and stability of long, relatively thick-walled metal tubes under combined bending and external pressure were studied through combined experimental and numerical efforts, and a suitable formulation of the problem based on the principle of virtual work was used to numerically simulate the experiments.

Inelastic analysis of thin-walled tubes under cyclic bending
P. K. Shaw,Stelios Kyriakides +1 more
TL;DR: In this paper, the authors presented a virtual work-type formulation of the problem in an attempt to analytically predict the growth of ovalization for tubes cycled in pure bending.
Journal ArticleDOI
Plastic mechanism analysis of circular tubes under pure bending
TL;DR: In this article, a theoretical treatment to predict the moment-rotation response of circular hollow steel tubes of varying D/t ratios under pure bending was described. But the model is based on elasto-plastic treatment, which is complex and difficult to use in any routine design.

An experimental investigation of the degradation and buckling of circular tubes under cyclic bending and external pressure
TL;DR: In this article, the effect of the cyclic bending history and of the external presdure on the rate of accumulation of ovalization and on the onset of instability was investigated and significant similarities were observed between the response and onset of the instability in the monotonic bending case and all cyclic lifting cases.
