Influence of porosity on ice dynamic behavior as assessed by spalling tests
Résumé
The impact of hailstones remains a major issue due to the damage caused by hailstorms against aeronautical or space structures. During a such impact, an intense fragmentation develops in the hailstone due to dynamic tensile loading at high strain-rates which influences the mechanical loading transmitted to the impacted structure. Up to now, the work of Saletti et al. (2019) is the only survey providing a robust and reproductible set of experiments about the dynamic tensile strength of ice, however the microstructure influence was out the scope of this experimental study.
