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.
