Modeling A ============== Characteristics of modeling ----------------------------------- The model consists of 2 plates corresponding to the mean plane of the 2 layers of the reference model. To represent these 2 plates, we start from the mesh of the mean plane of the bilayer that we offset from the distances :math:`-0.05m` and :math:`0.05m`. The elements used are plate DKT elements. .. image:: images/10000000000001E3000000F645F22D7AA1509166.png :width: 3.4752in :height: 1.7083in .. _RefImage_10000000000001E3000000F645F22D7AA1509166.png: The behavior 'ELAS_COQUE' is assigned to each of these plates corresponding to the homogenized orthotropic behavior of the corresponding layer. The values of the material coefficients entered under 'ELAS_COQUE' were calculated directly [:ref:`U4.43.01 `], page 27. Characteristics of the mesh ---------------------------- The model has 87 knots and 140 triangular DKT elements.
