Description:
This problem includes two tools, a punch nose and a die tube.
A blank tube is formed by blow molding the nose through the tube.

Model:
The hollow tube blank is made with 600 shell elements AND has an outer radius
of 12.06 mm, an initial thickness of 1.37 mm, and an initial length of 53.5 mm.
The internal pressure of the hollow tube blank is 40 N/mm2 applied using the
*LOAD_SEGMENT keyword. The tools are rigid shell elements. Only 1/4 of the
system is modeled because of symmetry.

The motion of the punch nose and the end of the blank follow a linear motion
with a total displacement of 15 mm (*BOUNDARY_PRESCRIBED_MOTION).
