      The properties and behavior of the penetration process in elastic-plastic medium of the absolute rigid cylindrical bodies are studied by numerical simulation. Resistance force, stress distribution along cylinder end, cavity position and so on are studied depending on basic dimensionless parameters - Mach number M = V₀/C₀ and strength yield . Some problems are discussed concerning calculations of elastic-plastic flows in multicomponent, media.
