A Quick Look at Spall using Clustering Techniques

Abstract

This report delineates the analysis of spall produced by one round of a 3.2 inch precision shaped charge using ISODATA, a centroid method clustering algorithm. Clustering was performed on the three spacial dimensions, x,y,z, by which the spall had been collected. The mass of each particle which was a priori categorized as low, medium-low, medium high, and high was then associated with its particle (by category) according to the particle's cluster membership. In general, low mass particles clustered nearer to the center of dispersion than the high mass particles, a result which had been observed in earlier two dimensional regression analyses.
