摘要：

In the previous studies of EDD steel for direct drawing and redrawing operations, dies were designed and developed. Deep drawing and redrawing experimentations were also performed for different size of blanks at various temperatures i. e. RT, 150(degrees)C, 300 degrees C, 450(degrees)C on 1mm EDD steel sheets. Later on Material models were constructed in the Preprocessor of LS Dyna for both direct drawing and redrawing operations. Simulations were run by using material model Barlat-36 and visco-plastic thermal model 106 at various temperatures for various blank sizes. Results were extracted from the simulations like Punch Load, thickness distribution and temperature gradient and these results were compared with the experimental results and discussed the impact of each one.
