3. B modeling#
3.1. Characteristics of modeling#
This modeling is a compression test with a deformation 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:
DDL_IMPO = _F (GROUP_MA =” HAUT “, DZ = 1.0E-04), **
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.
3.2. Tested sizes and results#
The observed quantity is constraint SIZZ.
