C modeling
==============


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

The crack is modelled using the X- FEM method. We use C_ PLAN modeling and the CALC_G_XFEM operator.


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

The mesh contains 96000 elements of type QUAD4.


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

Dynamic stress intensity factors :math:`{K}_{I}(t)` and :math:`{K}_{\mathit{II}}(t)` to :math:`t\mathrm{=}2.E\mathrm{-}3\mathit{sec}` are tested.
