5. Summary of results

Through the calculation with the two models, qualitatively, we find the pressure maxima at the right times and the return to rest after the wave has passed.

The results obtained with operators DYNA_VIBRA and DYNA_NON_LINE are very similar. The difference comes from obtaining at each time step the state of balance of the efforts of the second member with the operator DYNA_NON_LINE. However, this difference is still minimal because the time step used with DYNA_VIBRA is small enough.
