Nonisothermal warm deep drawing of SS304: FE modeling and experiments using servo press
The International Journal of Advanced Manufacturing Technology, 2015 Experimental and viscoplastic finite element analysis (FEA) of thermo-mechanical plastic deformation in nonisothermal warm deep drawing is studied using SS304. A nonisothermal deep drawing tool is used in a servo-motor-controlled press. Drawability window of SS304 under elevated temperatures (25–225 °C) and low to high strain rates (drawing speeds of 2.

Analysis of Thickness Strain Prediction in Warm Deep Drawing of Ti-6Al-4V Alloy
Advanced Materials Research, 2014In this work, deep drawing experiments have been performed in order to study formability of Ti-6Al-4V alloy sheet at temperature ranging from room temperature to 4000C. It is found that below 1500C, formability of the material is very poor and above 1500C till 4000C, limiting draw ratio (LDR) is found to be 1.8 which is substantially lesser than other ...
