摘要

Small pyrex glass spheres, representative of stoney meteoroids, were fired into double-sheet structures at velocities to 24,000 feet per second to determine the effects of a number of target variables upon penetration resistance. It was observed that the impacts could be classified into various categories as a function of the impact velocity:a low-speed impact region, a transition region, and a high-speed impact region. The regions are discussed and illustrated by individual frames from high-speed motion pictures of the impact process. It is noted that results obtained in one region of impact are not applicable to the others.
