B modeling
==============

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

**Figure** 4.1-a **: B** modeling mesh**

Modeling: D_ PLAN

Boundary conditions:


* :math:`\mathrm{DX}=0.0\mathrm{mm}` out of :math:`45`,


* :math:`\mathrm{DY}=0.0\mathrm{mm}` out of :math:`12`,


* :math:`\mathrm{DY}=0.3\mathrm{mm}` out of :math:`34`.


Characteristics of the mesh
----------------------------

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


* SEG2: 92


* QUAD4: 260


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.

    "**Instant (s)**", "**Difference between the two curves (** :math:`\mathrm{kN}` **)**"
    "0.04", "1.66E-016"

    "0.8", "-1.43E-004"

These values are tested in non-regression.

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