Figure 3
Schematic sequence showing movement of a single prismatic loop (solid lines) from a side view under shock compression produced by impact of a flyer plate with velocity VF; (a) flyer plate approaching target containing prismatic loop; (b) shock front penetrating target and leading to large shear stresses; (c) shock front interacting with top portion of prismatic loop; (d) movement of top and bottom portions of prismatic loop in opposite directions. MD snapshots corresponding to the schematic representation are also shown. Color represents depth towards the page, with red closer to the observer. (a) Existing prismatic loop from nanoindentation; (b) shock propagating towards the loop; (c) upper portion of the loop moving towards the surface; (d) lower portion of the loop moving towards the back surface.
