摘要：
The results of investigations of the influence of high strain rates on yield stress of some structural metals are presented. Specimens from mild steel, high strength steel (HRA) and titanium alloy in the form of 2-mm thick sheet blank with regular parallel slits are used for impact compression tests in strain rate range up to 210(5) s(-1). The tendency of the yield stress to saturate with strain rate for all the metals tested was noted. Some patterns of deformation and failure of tested materials at such loading are shown.
