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


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

Elasto-plastic calculation on a plane stress model (C_ PLAN). A mesh adaptation is carried out at each time step, followed by a projection and balancing phase. For adaptation, software HOMARD is provided with a very fine description of the geometry of the hole in order to properly follow its outline. Otherwise, concentrations of non-physical stresses appear.


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

An initial mesh that includes 91 TRIA6 and 210 nodes is used.

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

We test the value of the stress components at the end of loading:
