Hugoniot measurement of diamond under laser shock compression up to 2TPa

Shock Compression of Diamond Crystal

Two shock wave experiments employing Lau• technique. The normal axis to the sample inclined mirrors have been carried out to surface of both crystals were very close to each determine the Hugoniot elastic limit (HEL), final other and inclined 15.4 ñ 0.6 ø from <111>, or 29.6 shock state at 191 and 217 GPa, and the post-shock ñ 0.6 ø from <110> in approximately the (110) state of diamond crystal...

Shock Hugoniot of H2O ice

[1] The outcome of impacts onto and between icy planetary bodies is controlled by the material response defined by the shock Hugoniot. New Lagrangian shock wave profile measurements in H2O ice at initial temperatures (T0) of 100 K, together with previous T0 = 263 K data, define five distinct regions on the ice Hugoniot: elastic shocks in ice Ih, ice Ih deformation shocks, and shock transformati...

Numerical Method for Shock Front Hugoniot States

We describe a Continuous Hugoniot Method for the efficient simulation of shock wave fronts. This approach achieves significantly improved efficiency when the generation of a tightly spaced collection of individual steady-state shock front states is desired, and allows for the study of shocks as a function of a continuous shock strength parameter, vp. This is, to our knowledge, the first attempt...

Calculation of Shock Hugoniot Curves of Precompressed Liquid Deuterium

Path integral Monte Carlo simulations have been used to study deuterium at high pressure and temperature. The equation of state has been derived in the temperature and density region of 10 000 ≤ T ≤ 1 000 000K and 0.6 ≤ ρ ≤ 2.5 g cm. A series of shock Hugoniot curves is computed for different initial compressions in order to compare with current and future shock wave experiments using liquid de...
