6. D modeling#

6.1. Characteristics of modeling#

We use 3D_SI and COQUE_SOLIDE models, linked by a LIAISON_MAILLE. We are in flexibility, linear isotropic elasticity, small deformations (ELAS/PETIT).

6.2. Characteristics of the mesh#

The part in 3D_SI modeling represents a quarter of the length of the beam, near the embedment. The rest of the beam is done in modeling COQUE_SOLIDE. The mesh is not coincident at the junction and this is done by a LIAISON_MAILLE.

The mesh is as follows:

  • Number of knots: 3816

  • Number of meshes and types: 720 HEXA9et 420 HEXA20

6.3. Results#

The results are compared to ssnv302a (3D overkill calculation), reference AUTRE_ASTER:
