Abstract—We propose a new mathematical model of high-speed penetration of metal jets, which makes it pos-
sible to describe two (elastic and hydrodynamic) stages of their penetration into high-strength barriers. The pro-
posed model describes both stages from unified positions and gives high convergence with experimental results.
