Abstract
Three crystallographically different types of fresh-water ice were tested to determine their mechanical properties at relatively high strain rate, their resistance to slow-speed penetration with a conical punch and their resistance to ballistic penetration by a conically tipped projectile. It was found that there is no correlation between either the tensile or compressive strength and the response to ballistic penetration. Slow-speed punching exhibited a similar lack of correlation with the mechanical properties and, for the ice types tested, required roughly three times as much energy to achieve a given depth of penetration as was required under ballistic conditions.
