Abstract: This paper presents a numerical study of the high-speed impact interaction of a steel ball with a two-layer metal target. The simulation was performed using the explicit finite element method. The Johnson-Cook model was used to describe the material behavior under intense plastic deformation and failure. Two target configurations were considered: "aluminum-copper" and "copper-aluminum". The influence of the layer arrangement on the penetration dynamics and the ballistic resistance of the structure was analyzed. It was found that the "copper-aluminum" configuration provides more effective absorption of the impact energy, which is manifested in a significant reduction in the residual velocity of the projectile and an increase in the ballistic limit velocity. The results demonstrate the critical importance of layer order optimization in the design of protective structures.
Key words: high-speed impact, two-layer plate, finite element method, Johnson-Cook model, numerical simulation, ballistic limit, copper, aluminum.
