Theory and Computations of Collapse and Jet Velocities of Metallic Shaped Charge Liners

摘要

A model is proposed to compute the collapse velocities of various elements of a metallic liner of a shaped charge from the known detonation properties of the explosive used and the geometrical configurations of the charge. The calculated collapse and jet velocities increase from the apex of the liner toward the base, reach a maximum, and then decrease monotonically thereafter. The calculated velocity distribution in the jet after it goes through compression agrees qualitatively and quantitatively with available experimental measurements. (Author)
