2. Benchmark solution#
2.1. Calculation method used for the reference solution#
Average between the results obtained with different codes (8 results in [bib1]).
2.2. Benchmark results#
Critical load values for both load cases.
2.3. Uncertainty about the solution#
The maximum deviation from the average of the results used is \(\text{2\%}\). This value is therefore associated with the uncertainty relating to the reference value.
2.4. Bibliographical references#
DEVESA: Treatment of large displacements in the angle element with 7 degrees of freedom implanted in Code_Aster, validation by a classical test case (HM‑77/94/079).
