Some Thoughts on Modelling Hail Impact on Surfaces

Abstract Hail impact-induced erosion has the potential to significantly affect operational lifetime of structures exposed extreme weathering environments such as hail events. Computational materials modelling can be used better understand behaviour during a hailstone impact, and here relevant background work is detailed. In this paper, an implementation ice impact model, utilising Smooth Particle Hydrodynamics along with highly strain-rate-dependent material shown, its results limitations discussed. An overview given on literature events, including history experimental work. The various methods which have been developed then given, evaluation suitability future in area.
