Although the maximum of the Von Mises stress is located in the material between the die, the distribution of Von Mises stress is non-uniform, the material located in the center part of the plate has smaller stress than the rest of that between the die.The main reason is that the material in the center part of the plate is only subjected to the force in the direction that the punch will move.
Because of the role of bending moment, the maximum stress occurred at the material between punch and die.
