| Abstract: | The JWL equation of state of detonation product for insensitive high explosive JB-9014 was further studied. The particle velocity, displacement, and acceleration of the cylinder wall were obtained from the modified standard cylinder test. The parameters of JWL equation of state were derived from analytical analysis and non-linear curve fit. The cylinder expanding process was numerical simulated using the ANSYS/LS-DYNA3D. The simulation results are consistent with the experimental results, which indicate that the parameters of JWL equation of state derived in this work are suitable and reliable. |
