Comportement mécanique dynamique de la glace : Contributions expérimentales et numériques pour le cas d'impacts de grêle sur structures aéronautiques

Abstract : The impactof hail on aircraft can cause significant damage such as leading edge perforations. In order to guarantee passenger safety, while optimizing structures, digital simulations can be a major advantage. However, the results obtained must be representative of reality. In this context, experimental tests of simulated hail ice (SHI) impacts are carried out. Coupled with a numerical impact study, experimental results enable to understand the phenomena involved during the impact of SHI. Then, the model proposed in the literature by Tippmann et al. (2013) is tested. Performances obtained are analysed. This analysis makes it possible to propose a new modelling approach in order to improve the results of the simulations currently proposed. In this perspective, a complete methodology for implementing the model and characterizing the material is proposed.
