The paper presents results of studies of shear strength of copper having various grain sizes under quasi-isentropic and shock-wave loading up to pressures P»40 GPa and P»70 GPa. The studies were performed for copper M1; large-grain copper with grain size d»100 mm; and ultradispersed copper with grain size d»0.5 mm. Basing on results of the experiments, the relaxation models of shear strength were developed. The model of shear strength of large -grain copper takes account for deformation heterogeneity. The first experimental data on strength properties of copper at pressure up to P»300 GPa were obtained by the perturbation method. © 2006 American Institute of Physics [ABSTRACT FROM AUTHOR]
