2. Benchmark solution

2.1. Calculation method used for the reference solution

The solution is the result of a calculation code and an experimental test.

From the reference solution valid for modeling the entire plate, it is necessary to divide the normal resultant by two to obtain a valid reference for a half-plate.

2.2. Benchmark results

The normal reaction force is as follows:

Imposed displacement (\(\mathrm{cm}\))	Reaction force (\(N\))
1.125	8.0083
2.2250	16.0166
3.3375	24.0250
4,4500	32,0333

The contact force is given as a reference. It is used to define validation tests, which are accompanied by non-regression tests with more stringent tolerances.

2.3. Uncertainties about the solution

These results are relatively approximate because they are recorded directly on the paper curve.
