6. D modeling#
6.1. Characteristics of modeling#
Q4GG modeling (QUAD4)
Boundary conditions:
. Side \(\mathrm{A2A4}\): \(\mathrm{DZ}=0\)
Symmetry conditions
. Side \(\mathrm{A1A2}\): \(\mathrm{DY}=\mathrm{DRX}=0\)
. Side \(\mathrm{A1A3}\): \(\mathrm{DX}=\mathrm{DRY}=0\)
The slab is symmetric with respect to planes \((X=0)\) and \((Y=0)\), the calculations are carried out on a quarter of the slab.
6.2. Characteristics of the mesh#
Number of knots: 169
Number of meshes and type: 144 QUAD4
6.3. Tested features#
The macro command POST_COQUE makes it possible to extract the forces and the deformations at any point in the shell.
