Crystal Structure and Equation of State of Shock-Compressed Soda-Lime Glass
Abstract
Crystal Structure and Equation of State of Shock-Compressed Soda-Lime GlassAbstractGlasses are widely used in many applications such as windows and shielding where they may be subjected to high-velocity impact. There is thus a strong interest in understanding their response to high strain-rate loading. In this project, we will use static and dynamic compression techniques to examine the behavior of soda-lime glass under extreme conditions. In particular, our effort will focus on understanding how the structure of the glass responds to compression at the atomic level. Static compression of soda-lime glass will be carried out to 60 GPa to determine the density evolution of the glass with compression. Laser heating will be performed at high pressures to determine the stable crystal phases that form from the glass. Shock-compressionexperiments will be carried out at both the Dynamic Compression Sector (DCS) of the Advanced Photon Source and the Institute of Shock Physics (ISP) at Washington State University. The DCS experiments will explore the lattice-level structure of phases formed under shock compression. The ISP experiments will provide the first measurements of the dynamic equation of state andother aspects of the continuum response up to 60 GPa. This multi-faceted approach will enable us to form a complete understanding of the behavior of the glass under dynamic loading at high compression.
