Modélisation A ============== Caractéristiques de la modélisation ----------------------------------- Le modèle est constitué de 2 plaques correspondant au plan moyen des 2 couches du modèle de référence. Pour représenter ces 2 plaques, on part du maillage du plan moyen du bicouche que l’on excentre des distances :math:`-0.05m` et :math:`0.05m` . Les éléments utilisés sont des éléments de plaque DKT. .. image:: images/10000000000001E3000000F645F22D7AA1509166.png :width: 3.4752in :height: 1.7083in .. _RefImage_10000000000001E3000000F645F22D7AA1509166.png: On affecte le comportement ‘ELAS_COQUE’à chacune de ces plaques correspondant au comportement orthotrope homogénéisé de la couche correspondante. Les valeurs des coefficients matériau introduites sous ‘ELAS_COQUE’ont été calculées directement [:ref:`U4.43.01 `], page 27. Caractéristiques du maillage ---------------------------- Le modèle a 87 nœuds et 140 éléments triangulaires DKT.
