Effect of Strain Rate on Fracture Initiation
This project focused on two key ways of improving armor design. The first method is by improvement of analysis through the development of testing techniques relevant to high-yield-strength steels under high strain rates and states of stress relevant to armor applications. This effort resulted in a novel method of testing steels under a variety of strain rates in which punch tests are performed in a drop tower. It also resulted in a proposed strain-rate dependent fracture locus. The second way that it contributed to improved armor design is that it investigated the efficacy of multi-steel armor as compared to traditional armor made out of only one grade of steel. It is shown that either a weight savings or gain in performance can be achieved by creating a multi- steel armor of different grades of steels through the thickness.
