4. B modeling#
4.1. Characteristics of modeling#
The beam part is modelled by elements from TUYAU. The shell part is modelled in DKT.
4.2. Characteristics of the mesh#
Number of knots: 4420
Number of meshes and types:
1 mesh POI1 (modeling DIS_TR),
1344 QUAD4 stitches (DKT modeling), 32 SEG2 stitches on each edge of the shell
4 SEG3 (TUYAU) stitches
4.3. Tested values#
Displacements and rotations at point \(\mathrm{P2}\) (to be multiplied by \(1.E-10m\)).
