3. Modeling A#

3.1. Characteristics of modeling#

The model consists of 2 bi-layer plates corresponding to the mean plane of the quad-layer of the reference model.

To represent these 2 plates, we start from the mesh of the mean plane of the quadrilayer that is offset from the distances \(\mathrm{-}0.1\) and \(0.1\).

The elements used are plate DKT elements.

3.2. Characteristics of the mesh#

The mesh is regular.

We have 10 subdivisions according to \(x\) and 5 subdivisions according to \(y\); a total of 50 DKQ (quad4) meshes and 66 knots.
