5Elastic (Sel ) and plastic (Spl ) Hugoniot
curves. The corresponding to previous slide
segment of MD Sel covers the pressure range
7.433 GPa. Markers circles obtained by MD
calculations. The lower circle with P 7.4 GPa
corresponds to the lower circle on previous slide.

7Propagation from left to right of an elastic
precursor and plastic front at in?uence of an
laser pulse with conditions from work R. Evans,
A.D. Badger, F. Fallies et. al., Phys. Rev.
Lett., 77 (1996) 3359. MD - a continuous
curve, 2T-hd - a shaped curve. The elastic zone
with the thickness del 70 nm between an elastic
shock wave (jump on the right) and plastic front
(jump at the left) is noted by a bilateral
horizontal arrow. The boundary between Al ?lm d
film 400 nm and glass is shown by vertical line
