The paper studies the behavior of ceramic porous tungsten alloy with reinforcing agents under the shock-wave loading conditions. Penetrating capacity of tungsten kinetic energy projectiles is calculated and experimentally investigated during their high-speed impacts on steel plates. It is shown that the increased penetration depth of tungsten projectiles exceeds that of the prototype with relevant weight and size, made of tungsten-nickel-iron cast alloy. A mathematical model is developed together with the design technique of the behavior of tungstennickel-iron-cobalt metal foams alloyed with boron carbide, tungsten titanium carbide and tungsten carbide during the high-speed impact interaction. The composite ceramic material is described here as a porous medium. The matrix of this medium is a homogeneous two-phase mixture of the tungsten-nickel-iron-cobalt system and reinforcing agents added in the required proportions. [ABSTRACT FROM AUTHOR]

The paper presents the methodology elaboration for the investigation of a high-speed impact interaction between the projectile and a split target. The impact interaction speed ranges between 1500 and 2500 m/s. The split target consisting of a polymethyl methacrylate target and a witness target made of D16 aluminum alloy, is placed at a 60 mm distance from the latter. Using mathematical simulation, all effects that occur during the high-speed impact interaction, are analyzed more precisely. [ABSTRACT FROM AUTHOR]
