Abstract:
The shock-wave loading of a gradient mixture is numerically investigated in the pressure range of 20–150 GPa. The shock compression of a platelet gradient mixture of tungsten and porous copper is considered using a model which is a modification of the model of platelet porous materials supplemented with an algorithm for calculating changes in the thermodynamic and kinematic parameters of each particle and the sample as a whole. It is shown that the calculated parameters of the state of this shock-compressed mixture in the pressure–particle velocity coordinates are consistent with experimental data for a real tungsten–copper mixture.
Keywords:
mixture, gradient materials, shock waves, high pressure.
