Some study on wrinkling behaviour of commercially pure aluminium sheet metals of different grades when drawn through conical and tractrix dies

Effect of bulge shape on wrinkling formation and strength of stainless steel thin sheet

“…It was well established that the use of a conical die can enhance the limiting draw ratio compared with that obtainable in a conventional drawing operation. Then, Narayanasamy et al [5] attempted to use tractrix die for the same material. The effects of the hot rolling conditions on the deep draw-ability of hot rolled IF steel were investigated by Zhao et al [6].…”
