Modeling A
==============


Characteristics of modeling
-----------------------------------

We use a MEMBRANE modeling in large deformations (DEFORMATION =' GROT_GDEP ') with the Saint Venant Kirchhoff law of behavior (RELATION =' ELAS_MEMBRANE_SV'). Linear elements are used.


Characteristics of the mesh
----------------------------

The mesh contains 108 elements of type QUAD4 and 14 of type TRIA3.

Tested sizes and results
------------------------------

We test the displacement in the center of the disk, in O.

    "**Identification**", "**Reference type**", "**Reference value** (:math:`\mathit{mm}`)", "**Precision**"
    "Point :math:`O` - :math:`\mathit{DZ}` ", "'SOURCE_EXTERNE'", "2448"," 1.5%"



notes
---------

We used linear research (RECH_LINEAIRE) to achieve convergence.
