To avoid rigid body movements, it is mandatory that the movements :math:`\mathrm{DY}` of the points :math:`\mathrm{A1}` (belonging to the blank) and :math:`\mathrm{A2}` (belonging to the punch) be identical.

notes
---------

The law of behavior of the material constituting the sheet is given in linearized form.

The calculation no longer converges beyond 75% of the total load.
