Modeling A
==============


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

This modeling is a compression test with a stress imposed on a cube that is free to deform in the direction perpendicular to the load.

The load is imposed on side HAUT following 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**, **)**) **,

**)**,

**)**

During the time interval [:ref:`0.0, 1.0 <0.0, 1.0>`] the load increases.

During the time interval [:ref:`1.0, 35.0 <1.0, 35.0>`] the load is kept constant.


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

The quantities observed are the lateral deformations EPXX and EPYY which are equal.
