Mechanical analysis of the deformation produced by internal inversion on round tubes;

Tube inversion is a special metal forming process in which a tube, when subjected to axial compression, will undergo external inversion or internal inversion to form double-walled tubular components that are difficult to produce by any other manufacturing process.

This paper investigates some experimental study on internal inversion of aluminium alloy tube under axial load, analyzes some deforming phenomena and necessary explanation, discusses the characteristics about the inversion load and deforming modes.
