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 of their mechanical properties.

Warm deep drawing of aluminium sheet [PDF]
, 2003 Aluminium sheet drawing processes can be improved by manipulating local flow behaviour by means of elevated temperatures and temperature gradients in the tooling. Forming tests showed that a substantial improvement is possible not only for 5xxx but also for 6xxx series alloys.

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 ...
