When the box parts drawing, the materials of the radius region flow to the straight edge portion, the straight edge portion tangential shrinkage in the flange area( εθ < 0 ), so that the strain strength of straight edge portion increases , and the degree of hardening of the material increases[4].
The closer to the straight edge central, the less materials of rounded area flow, therefore, the smaller hardening degree of the material.
