Hydroforming Characteristics of Double Layered Tube [PDF]

open access: yesTransactions of Materials Processing, 2007
Double layered tube is assembled with an inner tube and an outer tube, similar in material or not, contacting closely and deforming simultaneously when subjected to external force. For the manufacturing of double layered tube, the hydroforming assembly technology has several advantages.

Preform Design for Tube Hydroforming Based on Wrinkle Formation

open access: yes, 2011
A two-stage preforming process based on wrinkle formation is developed for the tube hydroforming process to accumulate material in the forming zone, thus reducing the thinning rate and improving the formability. In preforming stage one, the wrinkle onset
