摘要
Plate impact experiments have been performed in forward and reverse impact configurations on dry, quartz sand to obtain Hugoniot data. In the forward configuration, manganin gauges were placed both in surrounding anvils and in the sand. Gauges placed directly in or near the sand gave anomalously high stress values compared with stresses measured in the anvils. Shock wave velocity was calculated from time of arrival and the Hugoniot data inferred. This was found to agree with data from reverse impact and that previously published.
