Reference solution for modeling A
============================================

Calculation method
-----------------

The reference solution is obtained from equivalent simulations with the Hujeux model carried out. 
with the Finite Element Method calculation software, GEFDyn, developed at École Centrale Paris.

Reference quantities and results
-----------------------------------

The reference quantities and results provided by GEFDyn are as follows:

* Evolution of shear stress during loading.
* Evolution of plastic volume deformation.

Uncertainties about the solution
----------------------------

The uncertainties in the solution are directly linked to the precision required to reach the convergence of numerical calculation r
made with GEFDyn, which is :math:`1\times10^{-6}` as a relative norm on travel.
