3. Modeling A#
3.1. Characteristics of modeling#
The plate consists of 25 QUAD4 meshes modelled in DKT.
3.2. Comparisons and results#
3.2.1. Comparisons#
Comparisons are made on the components \(\mathit{DX}\), \(\mathit{DZ}\) and \(\mathit{DRY}\) of the displacement of the point \(\mathit{P2}\) as well as on the \(\mathit{SIXX}\) component of the stresses of the mesh \(\mathit{M1}\) (POINT 1, SOUS_POINT 1, this sub-point is located at the lower end in the thickness of the shell).
The following 4 figures compare the changes in these values over time for the two calculation codes.
3.2.2. Tested results#
The results tested correspond to the values compared above to the second peak, i.e. for times around \(\mathrm{0,042}\mathit{ms}\) (the times are slightly different depending on the quantities).
