Shock Initiation Studies on Heterogeneous Explosives

摘要

A set of laboratory experiments and a modeling analysis to determine and characterize the shock initiation behavior of high explosives are described. The experimental techniques include modified wedge tests, in situ manganin pressure gauge measurements, and multichannel visible radiometry on explosive samples shock loaded with an electric gun. A description of the experimental methodologies and limitations is made examining the effect of particle size in the shock initiation of HMX/water mixtures. The theoretical analysis is based on reactive flow hydrodynamic calculations using a three term ignition and growth model. 14 refs., 10 figs. (ERA citation 13:034792)
