8. F modeling

8.1. Characteristics of modeling

The models tested are DIS_T on SEG2 meshes. The stiffness characteristics of the discretes are therefore of the type: K_T_D_L, M_T_D_N.

8.2. Characteristics of the mesh

Number of knots: 3, number of stitches: 2, elements SEG2: 2, elements POI1: 1.

8.3. Boundary conditions and loads

Nodes N1, N2, N3 are locked in the X direction.

Nodes N1 and N3 are subject to displacement \(U(t)\), speed \(V(t)\), and acceleration \(\gamma (t)\) in Y and Z directions.

Travel conditions are functions of time:

\(\mathit{Depl}={U}_{1.}\mathrm{sin}(2\mathrm{\pi }.{f}_{1}.t)+{U}_{2.}\mathrm{sin}(2\mathrm{\pi }.{f}_{2}.t)+{U}_{3.}\mathrm{sin}(2\mathrm{\pi }.{f}_{3}.t)\)

Following the direction \(Y\): \((u,f)=[(\mathrm{0.20,0}.80),(\mathrm{0.15,1}.50),(\mathrm{0.10,3}.00)]\)

Following the direction \(Z\): \((u,f)=[(-\mathrm{0.20,0}.90),(\mathrm{0.15,2}.00),(-\mathrm{0.10,2}.80)]\)

The speed condition as a function of time: \(V(t)=\dot{U}(t)\)

The accelerating condition as a function of time: \(\gamma (t)=\ddot{U}(t)\)

8.4. Tested sizes and results

The quantities tested are the displacements in the plane, the forces in the plane, the dissipation.

Tolerances are by default.
