7. Summary of results

Comparing the results of the four models to the analytical solution, we observe:

• DKTG: maximum \(\text{5 \%}\) difference for travel, and \(\text{8\%}\) for the moment and curvature.

• Q4GG: maximum \(8\text{\%}\) difference for travel, and \(3\text{\%}\) for the moment and the curvature.

We can therefore consider that these models validate modeling DKTG and model GLRC in elastic behavior, Q4GG modeling and model ELAS.
