CUTOFF OF FRAGMENTED SHAPED CHARGE JET PENETRATION IN THE ABSENCE OF RADIAL DRIFT

摘要

Finite difference modeling of the penetration by a fragmented shaped charge jet indicates that there are perturbing effects at all jet velocities which may lead to early penetration cutoff in the absence of radial drift. It is likely that copper vapour is generated and involved near the end of penetration. A relationship between the time that penetration stops and the slope dL/dV of the jet shows promise as a penetration predictor. The model assumes resonance between the stream of fragments and the cavities in the penetration hole.
