Abstract

Abstract

By using the precision shaped charge warheads with the caliber of 36mm, anti-penetration experiments were conducted on the explosive reactive armors(ERAs)encapsulated by three different material layers with the same equivalent thickness, respectively.And the encapsulation layers were made of alumina, silicon carbide and steel plates, respectively.The experimental results show that for this armor configuration, after passing the ERAs with alumina and silicon carbide plates, the penetration depths of the shaped-charge jets decrease 82%and 88%, respectively, which are comparable to those in the cases of steel plates.And the interactions of the jets with the ceramic and steel plates were simulated by applying the finite-element code LS-DYNA3D.The simulation results display that after interaction with the jets, the ceramic plates shatter and break into pieces from the edge to the center.And the interaction mechanism between the shaped-charge jet back and the steel plate is an intermittent disturbance, whereas it is a continuous disturbance with the ceramic plates.
