F4-I Design & Use of Structural Materials to Mitigate Explosive & Impact Threats (WSU Component)

Abstract: The goal of this project is to develop the concept for advanced shock-resistive high-strength materials and material structures, which are critical needs for minimizing explosive damages. Our approach is to investigate dynamic responses of materials subjected to large strains and strain rates and mechanical deformation, model shock wave propagations, and develop the most effective structure to mitigate explosive-blast shock waves.

This year, our efforts have been focused on carbon nanotubes (CNTs) - an ideal system not only for understanding shock wave-matter interaction in atomistic scales, but also for mitigation of strong shock waves via its huge anisotropy in shock impedance. Progresses have been made on two aspects: (i) understanding mechanical strength of single wall carbon nanotubes under static high pressures - critical information complementing shock wave studies and (ii) preparing oriented carbon nanotubes for shock wave experiments.
