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


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

D_ PLAN_SI modeling.


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

The mesh is obtained by SALOME.

Number of knots: 8

Number and types of meshes: 1 QUAD8, 4 SEG3.


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

The problem considered here is homogeneous, the constraints (or the internal variables) are therefore identical at the various gauss points.

The following values are recovered at time 0.5 and 0.7: the component :math:`{\mathrm{\sigma }}_{\mathit{yy}}` of the stress tensor ('SIEF_ELGA', 'SIYY'), the work-hardening variable :math:`\mathrm{\kappa }` ('VARI_ELGA', 'V1') and the porosity :math:`f` ('VARI_ELGA', 'V2') and the porosity ('', 'V2').

The following table summarizes the values obtained by the Z-set finite element calculation software.
