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


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

A D_ PLAN_GRAD_VARI modeling with a unique mesh, element QUAD8.

Loading in direction :math:`n\mathrm{=}(1\mathrm{/}\sqrt{\mathrm{5,}}2\mathrm{/}\sqrt{5})`.


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

Number of knots: 8

Number and types of meshes: 1 QUAD8, 4 SEG3


Quantities tested and results of modeling A
----------------------------------------

The damage is tested at three nodes of the mesh, the value at the nodes being obtained by extrapolation (CHAM_NO 'VARI_NOEU', component V1) as well as the deformation energy after the compression phase.
