Computer Simulation of a High Explosive Cratering Experiment in a Complex Multilayered Geology

摘要

Computer codes were used to simulate a 42-GJ (10 ton) high explosive cratering experiment in a complex, multilayered geology. The calculated predictions were compared to actual dynamic experimental measurements taken well within the final crater radius. Geologic layering interaction has a definite effect on energy coupling, shock propagation, and final crater dimensions. Results from the various computer codes agreed well with the experimental results. This study significantly broadens the theoretical approach to high explosive cratering problems and will aid future investigations in the field.
