10. H modeling#

10.1. Characteristics of modeling#

The plate is modelled with a complete mesh (unlike substructuring). The mesh has 1200 QUAD4 meshes, which corresponds to twice the size of modeling A.

10.2. Sizes tested on the complete structure#

We test the natural frequencies:

We also test the modal deformations of the third and fourth modes (identified by the indices \((\mathrm{1,2})\) and \((\mathrm{3,1})\) respectively), by recovering the component \(\mathit{DZ}\) of the deformation along three lines: the two median axes and the diagonal of the plate. Each line is discretized by 10 points.

The results are very satisfactory.
