1. Reference problem

1.1. Geometry

The geometry of the problem is irrelevant. You just need to know that the mesh contains at least:

• 3 named stitches: \(\mathit{M1}\), \(\mathit{M2}\) and \(\mathit{M3}\),

• 3 named nodes: \(\mathit{A1}\), \(\mathit{A2}\) and \(\mathit{A3}\).

1.2. Material properties

Unimportant. We chose the VMIS_ISOT_CINE law of behavior, which has at least 3 internal variables.

1.3. Boundary conditions and loads

Unimportant.

1.4. Initial conditions

Unimportant
