THE CALIBRATION OF A COLLECTION MEDIUM FOR THE DETERMINATION OF PARTICLE VELOCITY

Abstract

A useful calibration of a medium for estimating particle velocities over a broad range of particle sizes, velocities, materials, and obliquities of impact is provided. Compact fragments of plastic, Mg alloy, Al alloy, steel, and W alloy have been used in single-fragment firings against fiberboard to produce the needed experimental data. A single empirical formula has been fitted to the data, relating striking velocity to the impact parameters of thickness of medium penetrated, angle of obliquity of strike, particle size, and presented area. An effort has also been made to determine limiting impact conditions for each fragment material for which the fragment will remain essentially intact during the penetration. Whenever the fragment breaks up or deforms excessively during the penetration, the velocity estimates are no longer valid.
