4. B modeling#
4.1. Characteristics of modeling#
To avoid rigid body movements, it is mandatory that the movements \(\mathrm{DY}\) of the points \(\mathrm{A1}\) (belonging to the blank) and \(\mathrm{A2}\) (belonging to the punch) be identical.
4.2. Characteristics of the mesh#
Number of knots: 182
Number of meshes: 131 QUAD4, 12 TRIA3 and 84 SEG2

4.4. 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.
