A Study of Hail Impact at High Speed on Light Alloy Plates

Abstract

An experimental investigation was made to study the effects of impact velocity, impact angle, plate material properties and thickness on the damage to flat light alloy plates caused by the impact of one inch diameter hail at speeds up to 2500 ft/sec, A description is given of the gas gun used for the firing of solid ice projectiles. Data are presented on indentation depth, dent profile and penetration for two aluminum alloys, L72 (25 ton/in 2, 15% elongation) and L73 (27 ton/in 2, 8% elongation) of thickness ranging from 0.028 inch to 0.0064 inch. Photographic studies of the impact phase are shown.
