Abstract:
A simulat ive experimental method of big length-radius ratio kinetic penetration bodies against reinforced concrete targets is proposed. Through a vertical penetration experiment against hal-f infinite-thick reinforced concrete targets with the 57 mm kinetic penetrat ion projectile whose speed ranges from 300 to 400 m/ s, the maximal penetration depth, hitting posture and other experimental parameters are obtained. The data acquired this way are compared with the data acquired through the experimental formula and they are basically ident ical. Those experimental data provide basis for the studies on the damage mechanism and the numerical simulat ion against the thick project . At the same t ime, through experimental studies on the damage effects, a method of damaging typical thick-project is found.
