Example: Rectangular Cup Drawing

Filename: mat_transversely_anisotropic.cup-draw.k

Description:
This problem includes three tools a punch, a holder and a die, and a blank.
The blank is drawn by moving the punch downwards to form around the die.
The blank uses the *MAT_TRANSVERSELY_ANISOTROPIC_ELASTIC_PLASTIC material model.

Model:
The *BOUNDARY_PRESCRIBED_MOTION_RIGID keyword is used to give the punch a
prescribed velocity in the z -direction. All shells on the holder are given
a pressure load to clamp down on the blank (* LOAD_SHELL_ELEMENT).
One way surface to surface contact is defined b etween the major parts in
the model. Because of symmetry, only 1/4 of the system is modeled.

Results:
A contour plot of the effective stress on the blank after drawing is shown.
