“…The "SLIDE" option sets the shearing gradients of mixed cells to zero and is indicative of what happens during a shock event for heterogeneous granular materials [6]. For the quartz particles, we assigned a Mie Grüneisen equation of state (EOS) along with a Von-Mises strength model with parameters and yield strengths found in literature and included with CTH [5,[8][9][10][11][12][13] The resolution maintained throughout the computational domain follows from literature [1], in that ten cells across each grain allows for convergence to a solution. Tracers placed at the driver sand interface, inside the sand, and at the sand window interface, helped to mimic the experimental setup as well as develop the shock Hugoniot states; each location contained 100 tracers.…”
