Modélisation C
==============


Caractéristiques de la modélisation
-----------------------------------


.. _DdeLink__788_9565909441:

Cette modélisation est un essai de compression avec une contrainte imposée sur un cube confiné (déformations transversales bloquées).

Le chargement est imposé sur la face HAUT suivant DZ:

**PRES_REP =** **_F(GROUP_MA='HAUT'** , **PRES =** **3.6187984804E+06)** ,

FCT **= DEFI_FONCTION(**

**NOM_PARA='INST'** ,

**VALE=(0.0** , **0.0** ,

**1.0** , **10.0** ,

**1000.0** , **10.0)** ,

**)**

L_INST **= DEFI_LIST_REEL(**

**DEBUT =** **0.0** ,

**INTERVALLE=(**

**_F(JUSQU_A =** **1.0** , **NOMBRE =** **5** , **)** ,

**_F(JUSQU_A =** **35.0** , **NOMBRE =** **340** , **)** ,

**)** ,

**)**

Pendant l’intervalle de temps [:ref:`0.0, 1.0 <0.0, 1.0>`] le chargement croît.

Pendant l’intervalle de temps [:ref:`1.0, 35.0 <1.0, 35.0>`] le chargement est gardé constant.
