4. Summary of results

4.1. Comparison with the elastic case

A graphical representation of the force-displacement response of the Lee gantry is presented above, where the response has been shown in the case of an elastic structure (obtained with the same modeling in Code_Aster).

It is interesting to note how the addition of elasto-plastic behavior completely modifies the response of the structure from the first plasticization.

4.2. Synthesis

Overall, the error committed during travel never exceeds 5%, which must be compared to the uncertainty about the solution, which is around 5%. Moreover, as explained, carrying out tests on values is difficult in the presence of control.

If we look at the figure above, we notice a good correlation between the reference response and that obtained by*Code_Aster*. In particular, the change in appearance due to the first plasticization is well described.
