Transitions between strong shock and elastic-plastic shock regimes in tin and Lennard-Jonesium.

We have recently developed the Continuous Hugoniot Method as an efficient numerical approach to study the front dynamics of steady shocks. This method produces a continuous set of shock states as a function of the shock strength driving parameter. We use our method to investigate the shock states at and near the transition between the strong shock and elastic-plastic shock regimes in both single-crystal tin and Lennard-Jonesium along the $\langle 100 \rangle$ directions.
