Popis: Velocity scaling is an experimental technique where substitute materials are employed to infer impact results for other materials at higher speeds. For example, impacts are conducted with cadmium at 5 km/s or zinc at 7.4 km/s to simulate the response of experiments with aluminum at 15 km/s. Despite a valid theoretical basis and compelling low-velocity experimental work, some questions remain about the technique because comparisons to the high speed impacts being simulated were heretofore unavailable. This paper combines the results of recent, high-velocity impact investigations and computational simulations to answer the question: Does velocity scaling work?
