From: The Quasi-Coarse-Grained Dynamics Method to Unravel the Mesoscale Evolution of Defects/Damage during Shock Loading and Spall Failure of Polycrystalline Al Microstructures

Figure 5

(a) The plots showing the decay of the compressive pressure at various times in the Z direction as the shock travels the metal for 3.2 µm grain sized polycrystalline Al system predicted by L64-QCGD simulation for a velocity of 1.5 km/s for the piston and pulse duration of 100 ps. The corresponding time evolution of (b) pressure and (c) void fraction shows the characteristics of incipient spall.
