Abstract
The dynamic yield strengths of three steels were determined at strain rates of about 103 s−1 and 106 s−1. The measurements at 103 s−1 were obtained by a new technique based on measurements of large amplitude elastic waves in long bars struck by rigid flyer plates. Embedded manganin gages were used to measure stress, and the gage records were long enough to observe subsequent reverberations between the bar free end and the plastically deformed impact end. The measurements at 106 s−1 were made with a slightly modified version of a conventional flyer-plate impact configuration. The data are combined with static results to show the behavior of these steels at strain rates of 10−3 s−1 to 106 s−1.
