This work presents a comparison between experimental data and numeric mesoscale simulations. The compaction of a mixture of Al-MnO2-Epoxy was simulated in a one-dimensional flyer plate configuration with the goal of determining the bulk shock Hugoniot. Mesoscale simulations, in which the initial conditions are imported from SEM images, reproduce the experimentally obtained bulk Hugoniot behavior. In addition the formation and evolution of hot spots are observed.
