Direct calculation of sound speed of materials under ramp wave compression

Direct calculation of sound speed of materials under ramp wave compression

Accurate loading-unloading sound speed of materials is indispensable for material equation of states and strength calculation at high pressure. In this paper, we propose an approach to calculate the loading-unloading sound speed of materials under ramp wave compression directly based on the characte...
