D modeling
==============

Validation of joint :math:`\mathrm{2D}` with the cohesive law CZM_LIN_REG


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

Modeling in plane deformations D_ PLAN for the elastic element.

Plane modeling for the joint element (keyword PLAN_JOINT).


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

Number of knots: 6

The elastic element is a QUAD4.

The joint element is a degenerate QUAD4 (knots combined).


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

The remark on control mentioned for modeling A also applies to this modeling.
