A STUDY OF THE BREAK-UP OF SHAPED CHARGE JETS

Abstract

Several possible explanations of the mechanism of the break-up of shaped charge jets are suggested. An approach using the assumption of visco-plastic flow is presented in detail. According to this approach, a constant area jet with linear velocity gradient breaks first at the tip, and then the break-up progresses back towards the rear. The average length of the fragments could be adjusted to two per cent of the original jet length if a coefficient of viscosity of 100 lb.-sec./sq. ft. were used.
