Numerical Study of Shock-Wave Loading of the W- and WC-Based Metal Composites

Shock-wave loading of metal composites (Elkonites) that represent sintered refractory materials (tungsten, tungsten carbide, or molybdenum) in combinations with low-melting metal (silver or copper) is simulated in numerical experiments. A thermodynamic equilibrium components model is employed. The simulated results are in good agreement with experimental data of several authors. The model describes dynamic loading of solid and porous alloys (Cu–W, Ag–W, Cu–WC, and Ag–WС) and allows selection of compositions of materials with different porosities and relative contents of components aimed at fabrication of solid and porous samples with desired characteristics under shock-wave loading.
