Patterned Armor Performance Against Multiple Impacts

Abstract

Two approaches have been taken to model the effect of multiple impacts on patterned armor. The first is a simple analytical model that assumes a uniform random distribution of impacts. The second is a more sophisticated computer model that allows for a Gaussian distribution of impacts around the aim point. The analytic model is used to show how areas of weakness in patterned armor can affect performance. In addition, the analytic model can be exercised to conduct quick trade-off studies between patterned armor concepts. The computer model, developed specifically to determine the effects of a small number of impacts, is used to calculate the effects of dispersion of impact points and aim point.
