Three-dimensional computer modeling of a shock-recovery experiment
An ideal shock recovery experiment would be to subject a sample material to a single, well-defined shock followed by a controlled, benign release of the stresses and velocities generated. The process should be such that any change found in the sample after recovery could be attributed to the shock process alone. In any real experiment with finite-sized samples, rarefaction waves are generated at the edges of the sample. In general these rarefaction waves can have a large effect on the sample, which is impossible to separate from the effects of the shock alone. It has been suggested that samples of certain shapes will have a small region in their interiors, which is substantially free from the effects of edge rarefactions. We will present the results of three-dimensional computer calculations done to test this hypothesis.
