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

:math:`E=195000\mathit{MPa}`

:math:`\nu =0.3`

Chaboche's viscoplastic behavior relationship (VISC_CIN1_CHAB)

:math:`N=3.5`

:math:`\text{UN\_SUR\_K}=0.001666667`

:math:`\text{UN\_SUR\_M}=0.`

:math:`\text{R\_0}=30.`

:math:`\text{C\_I}=2000.`

:math:`K=1.`


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

On :math:`A`: :math:`{u}_{x}\mathrm{=}{u}_{y}\mathrm{=}0`

On the :math:`\mathit{AB}` side: :math:`{u}_{x}\mathrm{=}0`

Loading:


1. Journey from 0 to point (:math:`{\tau }_{d}=146\mathit{MPa}`, :math:`{\sigma }_{d}=242\mathit{MPa}`) lasting 10 seconds,


2. Hold time at this point is 50 seconds.
