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


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

A D_ PLAN modeling with QUAD4 elements testing the functionalities of node-mesh contact with friction treated with the penalized method has been implemented.

The game between the skate and the frame is defined by a function using the keyword "DIST_2".

To avoid rigid body movements, the skate is held in place by springs of low stiffness:

    "RES_LAT ", ": :math:`k=2N/\mathrm{mm}`"
    "RES_HAUT ", ": :math:`k=\mathrm{0,005}N/\mathrm{mm}`"


Boundary conditions:

Free end of the springs: :math:`\mathrm{DX}=\mathrm{DY}=0`.

Built: :math:`\mathrm{DX}=\mathrm{DY}=0`.


Characteristics of the mesh
