2. Benchmark solution

2.1. Calculation method used for the reference solution

The membrane-type calculation with the non-eccentric plate is used as a reference. The non-regression with respect to the results obtained by this first calculation is verified.

2.2. Benchmark results

They consist of the values of the displacement field \(\mathrm{DX},\mathrm{DY},\mathrm{DZ},\mathrm{DRX},\mathrm{DRY}\) at the nodes \(\mathrm{N66}\) (for the DKT) and at the nodes \(\mathrm{N1}\) (for the DKQ) and the calculation of the frequencies of the first 4 modes.

2.3. Uncertainty about the solution

The uncertainty is zero since it is the same calculation carried out by two different methods.
