Abstract:

The jet formation caused by the collapse of a shaped charge liner is dependent upon the pressure delivered to the liner wall by the detonating explosive. As a shaped charge liner is collapsed axisymmetrically to the charge axis by a detonation wave to form a jet and a slug, the liner material experiences plastic deformation at exceedingly high strain rates. If the jet is presumed to form simultaneously on the axis, and then stretch uniformly, a one dimensional approximation shows that strain rates characteristic of this process are 10,000second. It is assumed that the jet is a ductile material which remains continuous during stretching. The purpose of this study was to determine the influence of explosive filler on shaped charge warhead performance.
