Plasticity

Good afternoon! I solve the plastic problem with respect to the well. I had difficulties with setting boundary conditions.

I set the static conditions easily:

CHARFIX=AFFE_CHAR_MECA(MODELE=MODE,
                 DDL_IMPO=(
                        _F(GROUP_MA='smx',
                           DX=0.0,),
                        _F(GROUP_MA='smy',
                           DY=0.0,),
                        _F(GROUP_MA='smz',
                           DZ=0.0,),
            ),
            );

Now I need to specify the conditions associated with the pressure. A year ago, when I solved a thermoelastic problem on the same grid, I did it this way:

CHAR=AFFE_CHAR_MECA(MODELE=MODELM,
                    DDL_IMPO=(
                        _F(GROUP_MA='smx',
                           DX=0.0,),
                        _F(GROUP_MA='smy',
                           DY=0.0,),
                        _F(GROUP_MA='smz',
                           DZ=0.0,),
            ),
                    PRES_REP=(
                        _F(GROUP_MA='duga',
                           PRES=0.0,),
                        _F(GROUP_MA='davl',
                           PRES=64.0,),
                    ),
            );

Now in connection with the plasticity, should I use the time function and DEFI_FONCTION, DEFI_LIST_REEL.. or set the conditions somehow differently? In all examples, conditions are set based on a known offset, but all I know is the boundary conditions for pressure, 0 and 64.

thank you in advance,
