dc.descriptionAbstract: This paper reports on the response of a floating saline ice sheet to penetration and perforation by 25.4-mm-diameter projectiles with three nose shapes: a full cone, a truncated cone and a full flat. Impact velocity was varied to produce behavior ranging from slight penetration to complete perforation of the 210- to 280-mm-thick ice sheet. The extent of crushing and fracturing adjacent to the path of the projectile was quantified, indicating the existence of a zone of crushing extending 1 to 2 body diameters into the ice sheet from the cavity wall. A series of shots into free-floating targets indicated that for penetrations of roughly two-thirds of the sheet thickness, the depth of penetration did not vary significantly as the target size was reduced to 24 body diameters. Tests on coated projectiles indicated that no significant abrasion occurred between the ice and the nose area of the projectile. Information is also presented on the effects of gun pressure, nose shape, average sheet temperature and angle of attack on the depth of penetration.-
