註釋

A high-velocity impact generally creates a crater in the structure, driving a strong shock wave into it. If the impacted structure, or target, is sufficiently thin, a puncture will result. If the target is relatively thick, the shock will rapidly decay into an elastic stress wave. When such a wave encounters a free surface, it is reflected, generally as a tensile wave, and its amplitude may be of sufficient magnitude to produce fractures near the surface. Such fractures may appear as granular cracks, as rear surface bulges, or as a complete detachment of target material, creating a shrapnel effect. An analysis of these phenomena is presented herein.
