A large number of experiments on the AISI 52100 steel spherical projectile penetration in thick targets made of 2024-T3 aluminum in the velocity range of 0.5–3.0 km/s was conducted. Projectiles with a diameter in the range of 2.5–5 mm were launched with a magnetoplasma light-gas ballistic installation. The dependence of the projectile penetration depth on the velocity was obtained, which has a non-monotonic form. Numerical simulation of crater formation in the studied material in ANSYS Autodyn was carried out. The Johnson-Cook plasticity model for 2024-T3 aluminium target and AISI 52100 steel projectile, and the Johnson-Cook failure model for the projectile were used. Based on the literature data, as well as selected experimentally, the constants of the material models which make it possible to describe the experimental data with high accuracy have been determined.
