Reference problem
=====================


Geometry
---------

The geometry is that of a material point.


Material properties
-----------------------

Young's module: :math:`E=190000\mathrm{MPa}`

Poisson's ratio: :math:`\nu \mathrm{=}0.3`

**Modeling A:**

MONO_VISC1: :math:`N=10` :math:`K=10` :math:`C=100000`

MONO_ISOT1: :math:`{R}_{0}=40` :math:`b=5` :math:`Q=0` :math:`H=0`

MONO_CINE1: :math:`D=4150`


Boundary conditions and loads
-------------------------------------

The load consists of a cycle of imposed deformation following :math:`x`:

To :math:`t=0`, :math:`{\varepsilon }_{\mathrm{xx}}=0`

at :math:`t=0.5`, :math:`{\varepsilon }_{\mathrm{xx}}=0.002`,

To :math:`t=1.5`, :math:`{\varepsilon }_{\mathrm{xx}}=-0.002`

To :math:`t=2.5`, :math:`{\varepsilon }_{\mathrm{xx}}=0.002`
