| Abstract: | An approach is proposed that allow constructing Hugoniots of molecular crystals of nitro compounds on the basis of data on their isothermal compression. Equations of state for PETN and TATB crystals are constructed for this purpose. The comparative analysis of experimental data on shock-wave compression of a simple PETN crystal and computational results is performed using the proposed approach to converting isothermal compression pressures to a shock adiabat and the constructed equation of state for PETN, presented in the work. As shown by the analysis, the experimental and calculated pressures lie within the limits of experimental error. [ABSTRACT FROM AUTHOR] |
