Modeling A
==============


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

Modeling in plane deformations (keyword D_ PLAN) for the cube with side 1.

Plane crack modeling (keyword PLAN_JOINT) for the joint element.

The cube is a :math:`\mathit{QUAD4}`.

The joint element is a degenerate :math:`\mathit{QUAD4}` (knots combined).


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

Number of knots: 6

Number and type of meshes: 2 :math:`\mathit{QUAD4}`.
