Finite element analysis of non-isothermal warm deep drawing of dual phase steel [PDF]
MATEC Web of Conferences, 2016 Improving the formability of the material is an important issue in the deep drawing process. Heating the material above its recrystallization temperature drastically increases formability but in the case of dual phase (DP) steels it results in the loss ...

Experimental and numerical studies on the warm deep drawing of an Al–Mg alloy
International Journal of Mechanical Sciences, 2015 Abstract The warm deep drawing of circular AA5754-O aluminium alloy blanks was investigated both experimentally using specially designed equipment and numerically using a fully coupled thermo-mechanical finite element model. Cylindrical cups were prepared with a heated die and blank-holder.

A numerical study on warm deep drawing of polypropylene
Polymer Engineering & Science, 2023 Abstract Warm deep drawing of polypropylene, a semi‐crystalline thermoplastic polymer, is studied using finite element analysis. In this process, a circular polypropylene blank is preheated to a temperature much below its melting temperature and deep drawn into the shape of a flat‐bottom cylindrical cup using a punch‐die combination ...
