**v6.04.504** SSNV504 - Extruding a piece of paper
============================================

**Summary:**

This test simulates the extrusion (without friction) of a piece of paper, a case frequently encountered in industrial shaping studies. The interest of this test is mainly to validate the "passage" of geometric singularities (acute and obtuse angles) and to test the consideration of two contact zones (multi-zone contact).

The models selected are as follows:


.. csv-table::

    "* Modeling A (AXIS):", "CONTACTnœud mesh, associated with mesh SEG2,"
    "* B modeling (3D):", "CONTACTnœud mesh, associated with QUAD4 meshes,"
    "* C modeling (AXIS):", "CONTACTnœud mesh GLISSIERE, associated with mesh SEG2,"
    "* D modeling (AXIS):", "CONTACT, CONTINUEassociée method with SEG2 meshes,"
    "* E modeling (AXIS):", "CONTACTnœud mesh GLISSIERE, associated with mesh SEG3,"
    "* F (3D) modeling:", "CONTACTnœud mesh GLISSIERE, associated with mesh QUAD4,"
    "* G modeling (3D):", "CONTACTnœud mesh GLISSIERE, associated with mesh QUAD8,"
    "* H (2D) modeling:", "CONTACT, method CONTINUEassociée with SEG3,"
    "* Modeling I (AXIS):", "CONTACTGLISSIERE, method CONTINUEassociée to SEG3,"
    "* J modeling (AXIS):", "CONTACTGLISSIERE, method CONTINUEassociée to QUAD4"
    "* K modeling (AXIS):", "Same as J modeling: ALGO_CONT = STANDARD + PENALISATION"


The models with GLISSIÈRE make it possible to maintain contact throughout the extrusion, mathematically. The result is physically similar to modeling without a slide, since it is a frictionless extrusion.
