2. Reference solution#

2.1. Calculation method used for the reference solution#

Not applicable.

2.2. Benchmark results#

Strictly speaking, there is no reference solution but a set of results from the Round Robin participants. These results are obtained by Finite Element calculations with different codes and using very different models: \(\mathrm{2D}\) (plane stresses, plane deformations), \(\mathrm{3D}\), small or large displacements, etc…

However, the numerical values tested in this test case come from a previous execution of Aster. It is a non-regression test case.

2.3. Uncertainty about the solution#

Not applicable.

2.4. Bibliographical references#
