| Abstract Scope |
Examining how a material behaves at a variety of pressures and temperatures is fundamental to comprehending its behavior and response when under extreme conditions. Current techniques like diamond anvil cells can investigate a material at only a single pressure at once, making collection of pressure-temperature states difficult to obtain. Shock experiments allow for obtaining these states along a Hugoniot. With this method, characterizing the microstructure using in-situ x-ray diffraction is challenging. Therefore, using molecular dynamics simulations provides a tool that can allow for examining material response under shock conditions at an array of temperatures and pressures. The interatomic potential used to predict these microstructures, temperatures and shock velocities determines the accuracy of the simulation. For this reason, this study and poster explores the ability of multiple interatomic potentials for Fe, Cu, Mg, and Ti to accurately capture and achieve Hugoniot states under shock loading conditions. |
