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

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

Here, shear loading is carried out under normal pressure.


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 tangential stress is compared with the reference solution at different loading times that correspond to different state of damage to the joint.
