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.


Characteristics of the mesh

Number of knots: 182

Number of meshes: 131 QUAD4, 12 TRIA3 and 84 SEG2

notes
---------

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

The calculations were carried out up to 6% of the load, they can continue without problems up to 78% of the total load, beyond that the calculation no longer converges.
