1.2. Meshing#

The mesh is made with 1 HEXA8.

1.3. Materials#

The material is BETON_RAG. Only the necessary characteristics related to the damage phenomenon are provided.

Do not not use the material characteristics of « BETON_RAG » of this test case to do studies. They are not physical, they are used for mathematical verification.

MAT = DEFI_MATERIAU (

ELAS =_F ( E = 32000.0E+06, #unité [Pa]

NU = 0.25, # without unit

),

BETON_RAG = _F (

# Mechanical Features

ENDO_MC = 1.95,**# without unit

ENDO_MT = 2.00,**# without unit

ENDO_SIGUC = 35.00E+06,**# unit [Pa]

ENDO_SIGUT = 3.18E+06,**# unit [Pa]

ENDO_DRUPRA = 0.15,**# unit [Rd]

),

)

1.4. Boundary and loading conditions#

1.4.1. For the cube free of lateral deformations#

The movements are imposed on the following faces:

  • BAS :DZ = 0

  • GAUCHE :DY = 0

  • ARRIERE :DX = 0

  • HAUT: imposed displacement as a function of time.

1.4.2. For the confined cube#

The movements are imposed on the following faces:

  • BAS :DZ = 0

  • GAUCHE, DROIT :DY = 0

  • ARRIERE, AVANT :DX = 0

  • HAUT: imposed displacement as a function of time.

1.5. Modeling#

The modeling is 3D.
