4. B modeling#
4.1. Characteristics of modeling#
4 POU_D_T elements with a full circular cross section: 4 SEG2 meshes
elements \(\mathrm{AC}\) and \(\mathrm{BC}\) |
radius \(R=7.978845{10}^{-3}m\) |
(area \(A=2.{10}^{-4}{m}^{2}\)) |
elements \(\mathrm{CD}\) and \(\mathrm{BD}\) |
radius \(R=5.641895{10}^{-3}m\) |
(area \(A=1.{10}^{-4}{m}^{2}\)) |
Poisson’s ratio: |
\(\nu =0.3\) |
Boundary conditions:
DDL_IMPO =_F (All=” OUI “, DZ= 0., DRX = 0., DRY = 0.)
To treat articulated connections, as many knots as bar ends are created.

at nodes \(\mathrm{A1}\), \(\mathrm{B2}\), and \(\mathrm{D4}\): DDL_IMPO =_F (All=” OUI “, DZ= 0. , DRX = 0. , DRY = 0.)
at nodes \(\mathrm{C1}\), \(\mathrm{C2}\), \(\mathrm{C3}\) and \(\mathrm{D3}\), \(\mathrm{D4}\) continuity of translations, by LIAISON_DDLDX and DY.
no rotation is imposed.
