J modeling
==============

Characteristics of modeling
-----------------------------------

Behavior tested: Iwan

The isotropic elastic properties of the material are:


* :math:`E=5.8\mathit{GPa}`


* :math:`\nu =0.3`


* :math:`\mathrm{\rho }=2764\mathit{kg}\mathrm{.}{m}^{-3}`

The parameters of the Iwan model (modeling B) are:


* :math:`{\mathrm{\gamma }}_{\mathrm{ref}}=2.00e-4`


* :math:`\mathrm{n}=0.1`


Tested sizes and results
------------------------------

The values tested are non-regression values because this test only verifies the possibility of plugging in a MFront law into KIT_THM.
