Al~ract--Deep drawing of a partially thickened blank, the thickness of which is somewhat larger at the punch head portion than at the flange portion, is investigated in an attempt to increase the limiting drawing ratio (LDR). A rigid-plastic finite element simulation is firstly used to predict the e

## Abstract Drawing of semi‐crystalline polymers generally involves a necking phenomenon, which is often referred to as plastic instability. The draw ratio in the stable neck is called __natural draw ratio__. A review is made of papers dealing with the phenomenology of necking and endeavors to iden
