摘要: Abstract Data are reported for hypervelocity impact cratering in glass arising from impacts of 1 mm diameter aluminium spheres impacting thick targets at 5.11±0.13 km s−1. The angle incidence the projectiles was varied 0° (normal incidence) to 80° (glancing incidence). crater resulting each measured and it found that size does not change significantly unless >45° normal. Crater shape (as given by ratios measurements, e.g. depth/diameter) is insensitive up extreme angles incidence.
