N modeling
==============


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

Isotropic multilayer plate (5 layers in thickness). Quadrangular shell element DSQ.

The plate model associated with the M model is rotated 20 degrees according to the alpha nautical angle and 30 degrees according to beta. The cell numbering is identical to that of M-modeling.
