What is it about?

The cross-section distortion and wall thinning are the most important defects which occur during the bending process of tubes. I analyzed these defects during the rotary draw bending process of aluminum alloy tubes by Finite Element simulation and experiments.

Why is it important?

In general, the maximum cross-section distortion and maximum wall thinning are located at the middle of the bending angle, in the so called critical cross-section. My study shows that in the case of rotary draw bending process, due to nature of bending process, the two defects are located not in the critical cross-section and not in the same cross-section.

Perspectives

The knowing of the tube deformation mechanism during the bending process is the first requirement when trying to minimize undesirable phenomena, such as cross-section distortion and wall thinning. My goal in this field of study is to find constructive solutions to improve the quality of the final products obtained by bending of tubes.
