“…As a prediction model of a spall failure a relative volume of a medium porous is used. A shear failure is preliminary, it does not pose the fragmentation of interacting bodies [5][6][7][8][9][10]. The material after failure is modeled by a loose medium (sand or dust), which is not capable of The numerical modeling technique in Eulerian spatial variables used in the present work is based on a two -step scheme of the predictor-corrector type and the method of discrete markers.…”

Abstract. The results of numerical simulations of a compact steel impactor with the aluminum porous shields under high-speed shock loading are presented. The porosity of barrier varies in wide range provided that its mass stays the same, but the impactor has always equal (identical) mass. Here presented the final assessment of the barrier perforation speed depending on its porosity and initial shock speed. The range of initial impact speed varies from 1 to 10 km/s. Physical phenomena such as: destruction, melting, vaporization of a interacting objects are taken into account. The analysis of a shield porosity estimation disclosed that the protection effectiveness of porous shield reveals at the initial impact speed grater then 1.5 km/s, and it increases when initial impact speed growth.

“…In some areas totally destroyed material, where the condition of a separated fracture, new surfaces, which divides the body into separate pieces. These fragments generally move (fly) with obviously different average speed [5][6][7][8][9][10]. As a research tool this study uses the method of numerical simulation based on 2-step method of second order accuracy in the Euler space variables [2,[9][10][11][12][13].…”

Abstract. In this paper we consider issues related to numerical modelling of processes of high-speed impact effect of a consistent series of damaging elements on the massive barrier. Research is carried out by comparing the finite speed of penetration of this series at a speed of penetration of the elongated one-piece (rod) of the missile of the same mass and diameter. Examines the range of initial impact speeds from 1 to 12 km/s taking into account such physical phenomena as fracture, melting and evaporation of the interacting bodies. The analysis showed that almost in all range of impact speeds segmented drummer is better solid elongated.
