Experimental and Finite Element Analysis on Rounded Corners Square Shape Tube Hydroforming Process [PDF]

open access: yesEngineering and Technology Journal, 2014
Tube hydroforming is a forming process where an inner pressure combined with axial feeding deforms the tube to the shape of a die cavity, i.e. the process state where the hardening of the material is unable to resist the increase in inner pressure and ...
