“…The agreement between the predictions and the experimental data is rather good. In figure 8, the experimental data for the instant corresponding to the measured peak force [8,29] are compared with the predicted duration of impact, t max , equation (2.11). The scatter for the data is relatively high.…”

This is a theoretical study about ice particle impact onto a rigid wall. It is motivated by the need to model the process of ice crystal accretion or damage caused by an ice particle impacts. A quasi-one-dimensional model of ice particle impact and deformation is developed. Spherical, cylindrical and conical shapes of the ice crystals are analysed. The model is able to predict particle residual height, the force produced by impact and the collision duration. The theoretical predictions agree well with the available experimental data.

“…On the contrary, mounting the pneumatic gun in a vertical manner would make the test scheme more complicated and increase the safety hazards. e horizontal test scheme was used successfully by several researchers [7,8,14,[24][25][26]. For the support system (boundary condition), the steel sheeting is screwed to timber battens spaced at 600 mm from each other and the projectile is aimed perpendicularly at the middle between the two battens.…”

“…A hailstone is an ice ball with a diameter greater than 5 mm [7][8][9][10]. Over 75% of hailstones are spherical, and they are generally found to have densities within the range of 700 kg/m 3 to 910 kg/m 3 .…”

Hailstorms pose significant risk for exposed building cladding materials. Steel sheeting is the most important cladding material used. The understanding of steel sheets behavior under hail impact loading is not sufficient for the manufacturing of hail-resistant sheets. With the purpose-built equipment, artificial hailstones of different sizes were launched to impact at steel sheets of different thicknesses and yield stresses as targets. A theoretical approach for the problem of predicting the dent size due to hailstone impact was developed and compared to the test results. The expressions developed in the theory can predict the dent depth before the impact, assuming the ratio between the dent depth and dent diameter is constant. The expression is not able to predict the depth of dents smaller than 0.75 mm and cannot predict whether the denting will occur or not. All hailstone sizes lead to visible dent on steel sheet of thicknesses 0.35 mm, 0.42 mm, and 0.55 mm. Visible denting was also obtained for the 0.75 mm steel samples with 45 mm and 55 mm hailstones; however, no denting occurred using 40 mm hailstones. It was found that the dent depth was inversely proportional with thickness and yield stress, while the dent diameter was found to be proportional to yield stress. As the yield stress of the steel sheet increased, the dent depth decreased for G300 and G550 steel. The dent diameter however increased as the yield stress increased. When the artificial hailstone shatters on impact, significant energy is lost and less energy is available to cause plastic deformation of the impacted material.
