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


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

We use a D_ PLAN modeling.

The contact between the half-ring and the block is frictional. The coulomb coefficient of friction is :math:`\mathrm{0,5}`.


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

The mesh contains 240 elements of type QUAD4.

Tested sizes and results
------------------------------

The movement is tested on two points in the contact zone. Point :math:`A`, located in the middle in :math:`X=125\mathit{mm}` and point :math:`B`, located in :math:`X=23/30\ast 250\mathit{mm}`, the aim being to always have one of the two points in contact during the calculation, despite the deformation of the half-ring.
