B modeling
==============


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

The loads and materials are identical to those in modeling :math:`A`.

Only the model of large deformations changes: here we compare SIMO_MIEHE with a VMIS_ISOT_LINE behavior (simulating elastic behavior, through a high elastic limit) and a UMAT behavior (also elastic) with GDEF_LOG.


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

The mesh is identical to that of modeling :math:`A`: 200 elements of type QUAD4.


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

Comparison of the results obtained with law SIMO_MIEHE with those obtained with GDEF_LOG.
