Introduction/purpose: The paper presents a numerical simulation of an impact of a 12. 7 mm projectile on an armored metal plate with a velocity of 500 m/s at a distance of 900 m. Numerical simulations offer the possibility of drastically reducing the time required to obtain results in comparison to the time required for planning. organization and execution of experiments. https://www.excellentphoto.shop/product-category/memory-card-reader/
