D modeling
==============


Characteristic of modeling
----------------------------------

The modeling used is two-dimensional under plane stress (C_ PLAN). The aim of this modeling is to validate the large deformation algorithm GDEF_LOG in C_ PLAN. We therefore compare the results with those obtained by GDEF_LOG in modeling :math:`C`, which treats an equivalent problem in 3D.


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

The mesh consists of a linear quadrangular mesh (with 4 knots).
