Example Problem 7
An experiment is set up in which a magnesium slab is shocked with a constant pressure
of 5.0 GPa. Determine
1. The particle velocity in the magnesium behind the incident shock before an
encounter with a free surface
2. The velocity of the free surface after the interaction
3. The particle velocity behind the surface after the interaction
4. The Lagrangian velocity of the leading edge of the rarefaction
5. The Eulerian velocity of the leading edge of the rarefaction
