In this study, the method of molecular dynamics simulation is performed to investigate the effect of voids on shockwave propagation in solid argon. The case study is a non-interactive solid modeled by Buckingham potential function. The shockwave is generated using the motion of a piston with different velocities in the solid that leads to increase the temperature after its propagation. The resulted shockwave velocity is in good agreement with the experimental data and the Hugoniot curve. It is also found that voids with different geometries and sizes lead to have the same temperature increment with less initiation piston velocity (less threshold initiation).
