WebJul 1, 2016 · Shock temperature seems to be correlated to the initial density, a well-known experimental fact: the more porous the graphite, the higher the shock temperature. We emphasize that the model uncertainty is rather narrow, a crucial information for the future … WebOur scaling law for porous ice showed about 5 times smaller than that for non-porous crystalline ice. This might be caused by the strong pres-sure decay in our porous targets [e.g., 10,11,12]. Post-shock temperature. Fig. 3 shows the example of the temperature changes (DT) with time at different distances (x), where DT is defined as the temperature Webthermoelectrons which are important in the shock compression of highly porous materials. This development led to new forms for the Hugoniot, the shock temperature, and the release isentrope. This paper has been written to compare calculations using the new model with previous modeling and experimental data for highly porous metals. dwighty l.moody prevailing peauer qoute
