Figure 4.1-a : Model A mesh

P04 Modeling: DKTG

Boundary conditions:

  • Embedding in \(\mathit{A1}\),

  • Simple support \(\mathit{A3A1}\) and \(\mathit{A2A4}\), that is, \(\mathit{DZ}\mathrm{=}0\) and \(\mathit{DX}\mathrm{=}0\).

Temporal integration:

  • Diagram: NEWMARK, formulation: DEPLACEMENT,

  • No time: \(1.{10}^{-4}s\).

4.2. Characteristics of the mesh#

Number of knots: 121, Number of meshes: elements QUAD4: 100, elements SEG2: 40.

4.3. Tested sizes and results#

We test the movements, speed and acceleration of point \(\mathrm{P04}\) at various times.
