4. B modeling#

This modeling tests the quadratic elements with the law of behavior VMIS_ISOT_LINE.

4.1. Characteristics of modeling#

Figure 4.1-a : B modeling mesh**

Modeling: D_ PLAN

Boundary conditions:

  • \(\mathrm{DX}=0.0\mathrm{mm}\) out of \(45\),

  • \(\mathrm{DY}=0.0\mathrm{mm}\) out of \(12\),

  • \(\mathrm{DY}=0.3\mathrm{mm}\) out of \(34\).

4.2. Characteristics of the mesh#

The number of knots is 297. The mesh consists of linear quadrangular elements:

  • SEG2: 92

  • QUAD4: 260

4.3. Tested sizes and results#

Figure 4.4-1 shows the force-displacement curves calculated with both methods. The values tested are differences in effort between the two methods at different times.

These values are tested in non-regression.

A least square criterion between the two curves is also used. Its value is: \(\mathrm{0,0949E-001}\).
