Microstructurally Engineered Armor System for Enhanced Survivability through Optimum Energy and Momentum Dissipation

Abstract

This project is focused on the optimization and development of a new class of high strength and lightweight aluminum alloys for armored systems subjected to high rate and severe loading conditions associated with IED events. The current effort is led by North Carolina State University (M.A. Zikry, D. Brenner, NCSU) An integrated experimental and atomistic and microstructural modeling framework has been developed and used to rapidly identify dominant microstructural characteristics that have been used to significantly improve ballistic response through tailored processing for desired applications. The project has resulted in new state-of-the-art in the aluminum armor alloy technology, and aims to develop very high mass efficiency aluminum armor alloys that are resistant to blast and penetrative events. This research is providing a critical link between macroscopic dynamic response, microstructural characteristics and inelastic mechanisms at relevant length and time scales. This basic research is being transitoned to the ARL-WMRD where it is being used to enrich parallel research efforts and help develop new and significantly improved armor designs.
