3. Modeling A#
3.1. Characteristics of modeling#
We use a DKT model with 3 layers in the thickness.
3.2. Characteristics of the mesh#
The mesh contains 5000 elements of type TRIA3.
3.3. Tested sizes and results#
We test the displacement along the \(Z\) axis and the moment \(\mathit{MXX}\) along \(\mathit{AB}\).
