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




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

Viscoelastic material: 3D modeling.

Steel material: modeling DKT (surface elements are the lower skin of the volume elements of the viscoelastic layer).

Aluminum material: modeling DKT (surface elements are the upper skin of the volume elements of the viscoelastic layer).

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

Number of knots 192

Number of meshes 349

 of which: elements SEG2 84

                         QUAD4 190

                         HEXA8 75




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

This modeling is used as a reference, so the tests are carried out only to verify the non-regression of the code.

The displacement values along the Z axis at point A are tested.
