Advanced Materials and Structures for Explosive Blast/Shock Mitigation
F4-I

Download the 2012 Project Report

The goal of this project is to develop a concept for advanced shock-resistive high-strength materials and material structures, which is critical for minimizing explosive damage. Our approach is to investigate the dynamic response of materials subjected to large strains and strain rates and mechanical deformation, model shock wave propagation, and develop the most effective structures to mitigate explosive-blast shock waves. Our efforts have been focused on carbon species such as carbon nanotubes, which are ideal not only for understanding shock wave-matter interaction on an atomistic scale, but also for controlling strong shock wave propagation via its huge anisotropy in shock imped­ance. In this year, we have made progress on (i) performing the first series of shock wave experiments on carbon species (both thin diamond and oriented CNT samples) and (ii) enabling technology devel­opment of time-resolved synchrotron X-ray diffraction, capable of probing structural and chemical evolutions of energetic materials undergoing combustion-like reactions in a µs time resolution.
