Computer Simulation of Dynamic Compaction
The shock compression of powder materials by high explosives using cylindrical geometry has been simulated with a two-dimensional computer program. The flow fields in the powders are analyzed for different initial conditions. An objective is to determine the design of the high explosive assembly to yield the desired pressure- time history in the powders. The calculations provided the means to translate results from one experimental geometry to another. An example is given for the compaction of a metallic glass powder.
