6. Summary of results

The results provided by Aster concerning the A and C models are close to the reference (difference \(\text{< 0.6\%}\)). In addition, the same results are found for models A and C; this is normal because the lower part remains elastic.

For B modeling, the differences in results between*Code_Aster* and the reference (SAMCEF) reach \(\text{3.3 \%}\) and come from the fact that geometric nonlinearities are treated differently in*Code_Aster* (by the command PETIT_REAC) and in SAMCEF.
