“…Satellites orbiting Earth are at risk of HVI through micro meteor orbital debris (MMOD). Yet on Earth, shaped charges are capable of launching jets of material at hypervelocity. Therefore, to protect human life and critical infrastructure from these hypervelocity impacts, a fundamental understanding regarding the responses of various materials at such high velocities is paramount. The HVI response of materials, particularly that of metals and ceramics because of their importance in space applications, has been investigated widely using a two-stage light gas gun (2SLGG). , The HVI impact of MMOD can lead to an ultrahigh strain rate, ≥10 6 s –1, and in 2SLGGs, an estimated strain rate over the range 10 5 –10 6 s –1 can be achieved …”

“…Estimates of fragment sizes are obtained by converting the measured pixel area to a spatial fragment dimension using an equivalent spherical particle assumption. An equivalent spherical particle assumption has been used by others in studying high velocity fragments [5,6].…”

“…Digital image processing has been used in particle tracking velocimetry (PTV) studies for detecting particles based on the pixel intensity levels of grayscale images and determining the particle centroid [5]. Image segmentation is performed to identify regions and extract the shape, pixel area, and centroids that represents the location of fragments in the shadowgraph images.…”
