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 $\cdot$ 10$^3$ 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$^\circ$C are given.

Keywords: spall strength, rupture strength, composite Hopkinson bar.
