Grahic Jump Location
The situation for 54 mm (a) and 69 mm (b) punch. The units of both axis are meter.
Grahic Jump Location
The normalized blank thickness for the final drawn cup, punch travel 82 mm. The thickness is plotted as function of the radial distance.
Grahic Jump Location
The pressure distribution at the draw die profile during the punch travel of the first test example. The position at the draw die profile is given in rad, where the die outlet is 0 rad.
