Dynamic Response and Energy Absorption Characteristics of Expansion Tubes Under Axial Impact
The expansion tube is normally used in impact-resistant components, owing to the stable expansion force, and high specific energy-absorption capacity. This paper reports the deformation mechanism and energy absorption characteristics of expansion tube ...

COPI vesicle transport is a common requirement for tube expansion in Drosophila. [PDF]
BACKGROUND: Tube expansion defects like stenoses and atresias cause devastating human diseases. Luminal expansion during organogenesis begins to be elucidated in several systems but we still lack a mechanistic view of the process in many organs.

Microstructure analysis and crack nucleation in TWIP steel tube at expansive deformation
The expansion test of twinning induced plastic (TWIP) steel tube was carried out at room temperature. Cracks appeared inside the tube edge when TWIP steel tube expands by 15.6%.

Evaluation and Prediction of Antifriction Effect Between Cold Expansion Cone and Inner Wall of Tube
It is difficult to evaluate the friction between the expansion cone and the inner wall of the tube in the expansion process.To solve this problem,a new cost-effective evaluation method was proposed.In this method,the expansion process of the expansion ...

Tube Expansion by Single Point Incremental Forming: An Experimental and Numerical Investigation
In this paper, we revisit the formability of tube expansion by single point incremental forming to account for the material strain hardening and the non-proportional loading paths that were not taken into consideration in a previously published ...

Expansion of oval tubes: prediction and experiment [PDF]
The manufacturing of oval tubes for automotive components from sheets consists of several steps, from the flat sheet to a tube with expanded ends. It involves roll-bending of tubes, welding and several expansion processes with segmented tools. Forming steps in this process are subject to springback after the release of tools.
