Characterization of the Material Microstructure for Reactive Material Design

Abstract

The aim envisaged in this project is the development and validation of numerical methods for the mechanical simulation of materials at grain scale. These methods shall enable predictive analysis of the dependencies of the mechanical properties -- especially the fragmentation behavior -- on the morphological and constitutive nature of a material at grain scale. Simulation capability of this kind can be effectively applied to design new materials with specially tailored mechanical properties. Specifically, this project is motivated by the aim to design (metallic) materials, which fragment under certain dynamic loading conditions into small particles, which can chemically react with a suitable ambient medium, such as shock heated ambient air or hot detonation products. Such materials could be effectively used to devise new or improved weapons with enhanced mechanical and/or thermal effects.
