In 1995, BMT Fleet Technology Limited (BMT) was contracted by DRDC to develop a behind armor debris (BA-debris) characterization and modeling system. The result of this project was Debris Characterization and Modeling, DeCaM 1.1 [1], a software capable of characterizing and modeling the BA-debris generated in ballistic penetration events. The current project undertakes to extend and improve the software’s analytic and predictive capabilities. The characterization and modeling processes within DeCaM were developed based on a combination of experimental, analytical and numerical techniques. The software was initially developed to provide a means of characterizing the debris generated in experimental kinetic energy projectile penetration test results. This characterization was based on the fragment penetration pattern as captured in standardized witness pack plates, located behind the target. The results of the DeCaM BA-debris characterization process includes estimates of the mass, velocity and location of all the fragments identified in the witness pack. The DeCaM modeling functionality is used to predict the characteristics of a BA-debris cloud, developed during a ballistic penetration event, based on a user specified shot condition and target system. The modeling process is a probabilistic simulation that is capable of providing results in deterministic form (one modeling result) or in a probabilistic form (multiple modeling results used to develop debris cloud statistics)
