Semi-empirical equations of state (thermal and caloric) are obtained to calculate not only the kinematic parameters (shock wave velocity, particle velocity, and reverberation of waves) but also the thermodynamic parameters (temperature, pressure, and compression) of monolithic and porous polytetrafluoroethylene at high shock pressures. The equations of state are used to model wave interaction in shock-wave experiments using the developed hydrocode. The equations are verified by comparison simulation results with published results of experiments and the data of our shock compression tests of solid and porous samples of PTFE in the range of 10–170 GPa. 相似文献

A model is presented for the electrical response of a polymeric electret in one-dimensional shock-wave loading, which incorporates
nonlinear effects in the response. Polyvinylidede fluoride is used to show that the model gives qualitative and quantitative
interpretation of experiments on such response up to pressures in one-dimensional shock compression of 60 GPa.

A new explicit analytical formula for calculating the temperature variation of elementary solids and fluids along the isentrope is proposed. The optimality of the formula is demonstrated by calculating unloading isentropes of liquid and solid diamond under shock compression and those of solid molybdenum and gold. 相似文献
