Abstract:

The SurvivabilityLethality Analysis Directorate of the U.S. Army Research Laboratory has a hierarchy of vulnerabilitylethality models including a compartment model, point-burst model, and stochastic point-burst model. The compartment model assesses the vulnerability of armored fighting vehicles by empirically-based damage correlation curves to evaluate probabilities of kill P sub ks and losses of function LoFs. The point-burst model considers a burst of behind-armor debris whenever perforation by the main penetrator occurs. Vehicle damage from the main penetrator and behind-armor debris is evaluated and combined using subjective damage-assessment lists to assess P sub ks and LoFs. The stochastic point-burst generates distributions of P sub ks and LoFs to estimate the probability of occurrence of any particular empirical test result. Recent concepts, such as vulnerability spaces new methodologies, such as degraded states and live-fire testing have significant implications for future modeling efforts. For instance, the historically nebulous distinction between P sub k and LoF is being addressed. Introductory studies and results using live- fire data suggest promising avenues to develop a more elementary low-level model. This report compares and contrasts the advantages, disadvantages, and applications of the existing vulnerabilitylethality models. Alternative modeling approaches are identified and the impact of ongoing research is assessed. Long-term recommendations for vulnerability modeling are specified.
