HYPERVELOCITY PERFORATION MECHANICS OF THIN METAL PLATES.
Abstract
An experimental investigation was conducted to examine hypervelocity perforation mechanics of thin aluminum and copper plates impacted at 5 to 7 km/sec by 3.18 mm spheres of like material. Flash radiography showed hole growth to be a two stage process with no 'rebound' of the hole periphery. Dissection techniques were developed to measure debris origin and velocity. High energy debris was found to depart the plates during the first stage of hole growth. Foil strain gages on the plates recorded less than 0.2 percent strain at 4.5 projectile diameters from impact. All results were compared with a representative 2D hypervelocity impact computer code. (Author)
