2.1. 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 [0.0, 1.0] the load increases.

During the time interval [1.0, 35.0] the load is kept constant.

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

The magnitude observed is deformation EPZZ.
