2. Benchmark solution#

2.1. Calculation method used for the reference solution#

The calculation with the bilayer material (command DEFI_COMPOSITE) is used as a reference. The non-regression with respect to the results obtained by this first calculation is verified. The two plates of the second modeling are eccentric with respect to the mean plane of the bilayer.

2.2. Benchmark results#

2.2.1. A and B models#

They consist of the values from the \(\mathrm{DZ}\) displacement field at point \(\mathrm{A3}\) and the generalized efforts at node \(\mathrm{A1}\). On the other hand, the 4 lowest frequencies of the structure are calculated.

2.3. Uncertainty about the solution#

For models \(A\) and \(B\), the reference solution is analytical. So there is no uncertainty.
