Modélisation A
==============


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

Cette modélisation est un essai de compression avec une contrainte imposée sur un cube libre de se déformer dans la direction perpendiculaire au chargement.

Le chargement est imposé sur la face HAUT suivant DZ:

**PRES_REP =** **_F(GROUP_MA='HAUT'** , **PRES =** **2.8278256400E+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.


Grandeurs testées et résultats
------------------------------

Les grandeurs observées sont les déformations latérales EPXX et EPYY qui sont égales.
