The LDR of the steel sheet were also calculated with data measured by Swift deep drawing cup experiment. The LDR of Swift deep drawing cup experiment and nu- merical simulation were compared and analyzed. Results show that the maximum deviation of LDR between the experiment and numerical simulation for DC01 steel sheet with various thicknesses is only 2.08%, the simulation numerical error is small. It is indicated that PAM-STAMP 2G software has high reliability and accuracy for LDR simulation of steel sheet.
