<p>The well-known method for determining the dynamic yield strength of metallic materials in the range of strain rates 10³–10⁵ s^–1 under impact compression is modified. The original method is a variation of the Split-Hopkinson Pressure Bar (SHPB) method. The modifications made it possible to expand the list of high-strength materials suitable for the study, simplify manufacturing, and reduce the cost of the specimen. Using the model material St3 steel, it was shown that the accuracy of determining the dynamic yield strength at strain rates up to 8×10⁴ s ^–1 does not deteriorate, and the modified methodology can be used to study high-strength steels. The methodology was tested on two highstrength steels, Swebor 500 (50 HRC) and 450 (45 HRC). The results of the impact compression tests are presented in the summary graph, which shows yield strength versus strain rate. These steels have similar dynamic yield strength characteristics. All the steels under study exhibit a significant increase in yield strength with increasing strain rate. At the same time, the yield strength of both high-strength steels increased by more than 1.8 times compared to their static values, and that of St3 steel by more than six times. The behavior of high-strength steels is peculiar: they exhibit a rapid increase in yield strength at strain rates ranging from 3×10³ s^–1 and reach a plateau above 2 GPa. This behavior is absent for St3 steel. A modified methodology is presented that enables the collection of new data to clarify the behavior of high-strength metallic materials under impact loading.</p>
