摘要
This work compares the estimates of shear strengths of aluminium nitride and titanium diboride obtained (a) from the simultaneous measurements of longitudinal and lateral stress by means of manganin gauges under plane shock wave loading with (b) those calculated from the offset between hydrodynamic and shock Hugoniot of these materials. The results of this work show that whereas the estimates of the shear strength obtained by these two methods for titanium diboride are consistent with one another, those of aluminium nitride are not. This is at least partly due to the observed inconsistency between the simultaneous measurements of longitudinal and lateral stresses in aluminium nitride.
