6. Example of use#
The following example is from test SDNS106A:
MAT = DEFI_GLRC (RELATION = GLRC_DAMAGE,
BETON = _F (
MATER = MAT_B,
EPAIS = EP,
GAMMA = 0.0,
QP1 = 0.15,
QP2 = 0.15,
C1N1=87.3E6, C1N2 = 87.3E6, C1N3 = 87.3E6,
C2N1=87.3E6, C2N2 = 87.3E6, C2N3 = 87.3E6,
C1M1 = 14.8E6, C1M2 = 14.8E6, C1M3 = 14.8E6,
C2M1 = 14.8E6, C2M2 = 14.8E6, C2M3 = 14.8E6,),
NAPPE = (
_F (MATER = MAT_A1,
OMX = 5.65E-4,
OMY = 5.65E-4,
RX=0.95,
RY = 0.95,),
_F (MATER = MAT_A1,
OMX = 5.65E-4,
OMY = 5.65E-4,
RX=-0.95,
RY = -0.95,),),
LINER = _F (
MATER = MAT_A2,
OML = 6.E-3,
RLR = -1.,),
CABLE_PREC = _F (
MATER = MAT_A2,
OMX = 4.56E-3,
OMY = 1.35E-2,
RX=0.0,
RY = 0.0,
PREX = -3.0E6,
PREY = -3.0E6,),
INFO = 2,);
Note:
In this example, 3 different materials are used: MAT_B (concrete), MAT_A1 (passive reinforcements) and MAT_A2 (metallic liner and prestress cables). Before defining the parameters of DEFI_GLRC, it is mandatory to use DEFI_MATERIAU to fill in all the parameters concerning these materials:
MAT_B = DEFI_MATERIAU (
ELAS = _F (
E = 30000.E6,
NAKED = 0.2,
RHO = 2500.0,),
BETON_ECRO_LINE = _F (
D_ SIGM_EPSI = 0.0,
SYT = 5E6,
SYC = -35.E6,),);
MAT_A1 = DEFI_MATERIAU (
ELAS = _F (
E = 2.E11,
NAKED = 0.0,),
ECRO_LINE = _F (
D_ SIGM_EPSI = 0.0,
SY = 3.E9,),);
MAT_A2 = DEFI_MATERIAU (
ELAS = _F (
E = 2.E11,
NAKED = 0.3,),
ECRO_LINE = _F (
D_ SIGM_EPSI = 0.0,
SY = 5.E8,),);
Although the homogenization formulas used in DEFI_GLRC only use the threshold values SY for ECRO_LINE and SYT, SYC for BETON_ECRO_LINE of DEFI_MATERIAU, it is necessary to also enter the values D_ SIGM_EPSI as indicated above, since these are mandatory keywords.
