2. Modeling A#
2.1. Characteristics of modeling#
This modeling is a tensile test under imposed deformation, 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,
10.0, 3.0, ),
)
L_ INST = DEFI_LIST_REEL (
DEBUT = 0.0,
INTERVALLE = (
_F (JUSQU_A = 10.0, NOMBRE = 50, ), ),
),
)
2.2. Tested sizes and results#
The observed quantity is the constraint SIZZ on the HAUTE face.
