Abstract: | Results of dynamic rupture tests of a series of metals obtained using a composite Hopkinson bar and shock-wave loading of
plane specimens are described. It is shown that the actual rupture strength at a strain rate of 5 · 103 sec−1 is very close to the spall strength at higher strain rates. Results of testing the same metals using a composite Hopkinson
bar within a temperature range of 20–350°C are given.
