Consideration is given to the setup and results of shock-wave experiments that recorded the longitudinal stress-wave profiles σxx in quartzite at the initial density ρ0 = 2.63 g/cm3. Profiles of the symmetric impact-induced stress waves were measured within 20–50 GPa by the method of the overtaking release wave in plane samples using manganin gauges built into quartzite. The objective of this effort is to measure experimentally the shock-wave properties of the rock, namely quartzite, as these results are needed to calibrate, further develop, and improve computer models of equations of state. This effort is of fundamental nature. Our task was to generate, with the help of low-resistance manganin gauges, profiles of longitudinal stresses σxx in quartzite sampled from the Pervouralsk deposit. Experiments were performed with the help of plane-wave generators and a two-stage light-gas gun. As a result, a series of experiments provided experimental “longitudinal stress – time” relations and the parameters of quartzite shock compression within 20–50 GPa, both being of great importance for the development of computer models. |
