Impact Response of Granular Material at Global and Meso Scales
Abstract
The objective of this research program is to develop fundamental understanding of the mechanical response of granular target materials under impact loading conditions at two scales: continuum level and particulate level. Complicated interactions between the granular target and a high-speed projectile may produce unexpected projectile motion. A physical and quantitative understanding of the granular material behavior will significantly contribute to the optimal manipulation of the projectile-target interactions in high-speed penetration. In this program, we conducted sand penetration experiments at global scale with the positions of the projectile monitored by flash x-ray. To observe variations in impact-induced pressure inside the sand target, we developed thin pressure sensors that are embedded in strategic locations and wireless communication system to wirelessly connect the sensors to data-acquisition systems.
