Abstract
In the present research, the behavior of 304L austenitic stainless steel in the deep drawing process
has been studied at the room temperature through experimental and nite element simulation method. Magnetic
method calibrated by XRD was used to measure induced-martensite. Martensite volume fraction in the various
portion of the deep-drawn cup under optimum blank holder force (BHF) and in the rupture location was evaluated.
Findings of the present study indicated that higher martensite volume fraction occurred in the ange portion in the
drawn cup due to higher strain and stress concentration in this area. Also, rupture happened at the arc portion of
the wall of drawn cup with higher blank diameter due to higher strain, work hardening, and martensitic transformation.
Both experimental and simulation results showed that maximum LDR of 2 obtained in the forming process.
All experimental procedures were simulated by LS-DYNA software, employing MAT_TRIP, and experimental results
were in good agreement with the FE simulation.
