Some thoughts on modelling hail impact on surfaces

Research output: Contribution to journalArticle

Abstract

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