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


Characteristics of B modeling
-------------------------------------

The mesh of the plate is composed of two parts:


* :math:`\mathrm{P1}`, made up of a non-eccentric mesh


* :math:`\mathrm{P2}`, made up of two superimposed meshes:


    * :math:`\mathrm{PLAQ}\text{\_}\mathrm{P1S}` offset from :math:`\mathrm{0.015m}`


    *

        .. image:: images/Shape3.gif


        .. _RefSchema_Shape3.gif:

:math:`\mathrm{PLAQ}\text{\_}\mathrm{P1I}` offset from :math:`-\mathrm{0.035m}`

Modeling DKT:

.. csv-table::

    "Number of nodes", ":math:`26` ", "", "", ""
    "Number of stitches", ":math:`21` ", "That is:", "SEG3 "," :math:`3`"
    "", "", "QUAD4 "," :math:`18`"


Node group:


* :math:`A,B,C,D,E,F,G,H`

Mesh group:


* :math:`\mathrm{PLAQUE}`: surface :math:`\mathrm{ACDF}`


* :math:`\mathrm{PLAQ}\text{\_}\mathrm{P1}`: surface :math:`\mathrm{BCDE}`


* :math:`\mathrm{PLAQ}\text{\_}\mathrm{P2}`: surface :math:`\mathrm{ABEF}`


* :math:`\mathrm{CD}`: segment :math:`\mathrm{CD}`


* :math:`\mathrm{FA}`: segment :math:`\mathrm{FA}`


* :math:`\mathrm{BE}`: segment :math:`\mathrm{BE}`

In this model, we test COEF_RIGI_DRZ negative. In this case, ddl DRZ has a physical meaning of "drilling rotation" or rotation around normal.
