3. Modeling A

3.1. Characteristics of modeling

3D beam element modeling: POU_D_T

Cutting:

\(\mathrm{AC}\) = 4 SEG2 stitches of equal length

Boundary conditions:

• Embedded \(\mathrm{N1}(A)\) knot

DDL_IMPO \(\mathit{DX}\mathrm{=}\mathit{DY}\mathrm{=}\mathit{DZ}\mathrm{=}\mathit{DRX}\mathrm{=}\mathit{DRY}\mathrm{=}\mathit{DRZ}\mathrm{=}0\)

• Node \(\mathrm{N5}(C)\) in imposed displacement following \(x\)

DDL_IMPO \(\mathrm{DY}=\mathrm{DZ}=\mathrm{DRX}=\mathrm{DRY}=\mathrm{DRZ}=0\) \(\mathrm{DX}(t)=\stackrel{ˉ}{u}\)

Resolution:

Newmark Direct Integration Algorithm

No time: \(\Delta t\mathrm{=}{10}^{\mathrm{-}5}s\)

Observation time: \(\mathrm{0,03}s\)

3.2. Characteristics of the mesh

Number of knots: 5

Number of meshes and type: 4 meshes SEG2

3.3. Tested sizes and results

• Move to the middle point \(B\)
