Armor Design Based on Material Properties,

Abstract

As a result of extensive research over the last 20 years, an analysis of high-rate loading and fracture has evolved that models the three main features of failure caused by stress waves. The nucleation and growth of voids are governing processes on which the model is based. In the following, a description, will be given of the characterization of a rolled homogeneous steel armor and a penetrator alloy in terms of this model. It will be shown by the results that the model is sensitive to the microstructural detail of the materials characterized. Finally, extensions of the model that are essential to the design of armor will be described along with an indication of how such a design is accomplished. (Author)
