Initial conditions, boundary conditions, and loading
----------------------------------------

**Phase 1:**

The sample is brought to a homogeneous state:

    :width: 620
    :height: 352


.. _RefImage_Object_1.svg:

, by imposing the corresponding confinement pressure on the front, right lateral and upper faces. The movements are blocked on the back sides (

    :width: 620
    :height: 352


.. _RefImage_Object_2.svg:

), left lateral (

    :width: 620

.. _RefImage_Object_3.svg:

) and lower (

    :width: 620
    :height: 352


.. _RefImage_Object_4.svg:

).

**Phase 2:**

We keep the movements blocked on the rear faces (

    :width: 620
    :height: 352


.. _RefImage_Object_5.svg:

), left lateral (

    :width: 620
    :height: 352


.. _RefImage_Object_6.svg:

) and lower (

.. image:: images/Object_7.svg
    :width: 620
    :height: 352


.. _RefImage_Object_7.svg:

), as well as the confinement pressure on the front and right lateral faces. An imposed displacement is applied on the upper face:

.. image:: images/Object_8.svg
    :width: 620
    :height: 352


.. _RefImage_Object_8.svg:

, so as to obtain a deformation

(counted from the start of phase 2).
