5. D modeling#
5.1. Characteristics of modeling#
This modeling is a compression test under imposed deformation, on a confined cube.
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,
10.0, -70.0, ),
)
L_ INST = DEFI_LIST_REEL (
DEBUT = 0.0,
INTERVALLE = (
_F (JUSQU_A = 10.0, NOMBRE = 100, )) **,
),
)
5.2. Tested sizes and results#
The observed quantity is the constraint SIZZ on the HAUTE face.
