Abstract
An attempt to model the shock-to-detonation behaviour of the explosive H-6 has been made. The Forest fire model of ignition was calibrated using experimental data. Simulations of polymethylmethacrylate (PMMA or plexiglas) and water gap tests were then made using DYNA2D into which the Forest fire model had been implemented. The results show that while the onset of detonation (critical gap thickness) can be predicted fairly well, the subsequent events, such as backsurface velocities of the explosive, are not accurately predicted.
