6. Conclusion and outlook

The study of the behavior of a structure subjected to the impact of a projectile can be handled by a variety of models, ranging from empirical relationships that are quick to implement to sophisticated models that may require several weeks' work, depending on the configuration. For a given context, the engineer must weigh up the stakes and uncertainties associated with this type of analysis (and in particular the assessment of projectile characteristics) against the choice of a resolution method. In addition, the choice must be adapted to the phase of the project. For example, the same level of precision will not be required in the pre-project phase as in the execution phase. Above all, it's important to be aware of the limits of the different approaches, particularly with regard to the representativeness of the simulations carried out. Increasingly high-performance computing resources are...
