Geometry
---------

P=3 MIN
This non-regression test case is the study of a simple geometric structure. The structure analyzed (FIG. 1,1-a) is a square element of unit dimensions (1 meter on a side) represented by plane elements with a side of 0.05 m. It is embedded in the base, a horizontal load equal to 3 MN is applied to one of the corners of the element.

Materials
---------

The reinforced concrete used for plane modeling corresponds to a linear elastic material with the following characteristics for concrete and steel.

Concrete:

.. csv-table::

    "Young's modulus", ":math:`E` ", "21 GPa"
    "Poisson's Ratio", ":math:`\nu` ", "0.2"
    "Elastic limit", ":math:`{f}_{\mathit{cm}}` ", "36 MPa"

Reinforcement steel:

    "Young's modulus", ":math:`E` ", "210 GPa"
    "Elastic limit", ":math:`{f}_{y}` ", "500 MPa"

Boundary conditions
----------------------

The massif is assumed to have a continuous embedment at the base. The loading is a horizontal force of 3 MN at the head of the plate (see Figure 1.1-a).
