Abstract
A shaped charge with ball-cone liner produced rod-like jet was studied by tracer-point processing techniques and LS-DYNA. Key parameters to evaluate the performance of jet, such as velocity distribution of material of liner, tip velocity of jet and penetration hole were obtained. The calculated result indicates that effective jet velocity of the general shaped charge with small degree liner is over 2000 m/s for steel target with general strength, while critical penetration velocity of rod-like jet is 1400 m/s, based on above, the conversion rate of rod-like jet was 29.65% for this shaped charge structure.
