摘要

Numerical simulations for penetration into C35 concrete by 27 kinds of shaped charges withdifferent cone angles, different liner thicknesses at different stand-offs were performedbased on AUTODYN-2D software in this paper. Titanium alloy with a density of 6.0g/cm3was chosen as liner material. The formations of shaped charge jets (SCJs) were studied andthe influence rules of liner thickness, cone angle and stand-off on penetration depth andborehole diameter of SCJs were analyzed. Predecessors’ theoretical research achievementswere discussed. Results show that large liner thickness is unsuitable for small cone angle,which results in poor penetration efficiency. SCJ formed by larger cone angle and properliner thickness is not very sensitive to stand-off distance, which has better penetration depthas well as borehole diameter. The penetration depth increases and crater diameter decreasesalong with the increasing of stand-off distance. These results show a great engineeringsignificance.
