Numerical Simulation on Sheet-metal Bending Forming Based on ANSYS/LS-DYNA

According to the theory of dynamic explicit algorithm,the bending stamping process of TZM-alloy sheet was simulated by software ANSYS/LS-DYNA.Based on the results,the process of sheet-metal bending forming was analyzed and the probable defect was predicted so that the die structure design and stamping process were tested whether they were reasonable or not.Meanwhile,the sheet forming quality shows that the friction coefficient was discussed.
