Abstract

Abstract

A shaped-charge jet compresses the target axially and radially simultaneously when the jet penetrates into a thick target, and then the axial penetration and radial crater growth occur. The research on axial penetration is abundant, but the research on radial crater growth is less and there is a certain error between theoretical prediction and experimental results. The radial crater growth equation of the shaped-charge jet was derived by considering the compressibility of the jet and target materials based on the compressible model of shaped-charge jet penetration and the Szendrei-Held equation. The main changes of equations are the stagnation pressure adopted value of the compressible model and the density changed with jet velocity. An approximate solution of the compressible model was given based on the Murnaghan equation of state in order to simplify the tedious calculation process of the complete compressible model, i.e., the calculation processes of stagnation pressure and density change were simplified. The prediction by this model is better than that by the Szendrei-Held equation compared with the experimental study of the shaped-charge jet crater growth in water. The main factors affecting the radial crater growth by the shaped-charge jet include jet radius, stagnation point pressure, target strength, target density at the stagnation point and shaped-charge jet velocity. This model can more accurately predict the crater growth of the shaped-charge jets penetrating into the compressible targets. It may be helpful to study the interference of shaped-charge jet penetration with liquid-confined structures.
