PROGRAMMING AND COMPUTING SERVICE FOR EVALUATION OF COMPOSITE ARMOR

Abstract

A program was written to compute the residual velocity for a given striking (initial) velocity for a composite of three (or two) layered materials within three different total weight limits, M, (18, 28, 38 oz/sq ft) at intervals of 2 oz/sq ft in order to locate optimum combinations for minimum projectile velocity of perforation. The resultant program considered all combinations of three materials (as well as two) varying the amounts of each from zero to the pertinent weight limits mentioned above. Material combinations of the form A B A (where A and B are material types) were also included. From the results of each combination of materials and weights for a given initial striking velocity the "ten best armor" combinations were obtained. These combinations would result in the lowest perforation velocities.
