4. B modeling#
4.1. Characteristics of modeling#
We use a DKT model with 7 layers in the thickness.
4.2. Characteristics of the mesh#
The mesh contains 2500 elements of type QUAD4.
4.3. Tested sizes and results#
We test the displacement along the \(Z\) axis and the moment \(\mathit{MXX}\) along \(\mathit{AB}\).
