1.2. Meshing#

The mesh is made with 1 HEXA8.

1.3. Materials#

The material is BETON_RAG. The necessary characteristics are those related to damage and creep phenomena.

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

1.4. Boundary, contact and loading conditions#

1.4.1. For the cube free of lateral deformations#

The following movements are imposed on the faces:

  • BAS :DZ = 0

  • GAUCHE :DY = 0

  • ARRIERE :DX = 0

  • HAUT: forced displacement or imposed constraint.

1.4.2. For the confined cube#

The following loads are imposed on the faces:

  • BAS :DZ = 0

  • GAUCHE, DROIT :DY = 0

  • ARRIERE, AVANT :DX = 0

  • HAUT: forced displacement or imposed constraint.

1.5. Modeling#

The modeling is 3D.
