Figure 4
Initial configuration of a pre-existing prismatic loop (red); and configuration of the prismatic loop after being driven by the shock front during 2 ps (blue), showing significant stretching.
The upper portion of the loop consists of a single edge component that glides in a single plane as shear stresses actuate. The lower portion of the loop consist of several edge components in a bowed arrangement, they collectively glide in a single plane each, preserving the bowed shape. The motion, growth and shape change of the prismatic loop is a complex three-dimensional process. We focus on the edge components of the loop, each gliding on a plane along a <111> direction, hence studying the process as an effective one-dimensional motion.
