4. C modeling#

4.1. Characteristics of modeling#

This modeling is a tensile 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, 3.0, ),

)

L_ INST = DEFI_LIST_REEL (

DEBUT = 0.0,

INTERVALLE = (

_F (JUSQU_A = 10.0, NOMBRE = 50, )) **,

),

)

4.2. Tested sizes and results#

The observed quantity is the constraint SIZZ on the HAUT face.
