Calculated shock pressures in the aquarium test Available to Purchase

A new method of analysis has been developed for determintion of shock pressures in aquarium tests on commercial explosives. This test consists of photographing the expanding cylindrical tube wall (which contains the detonation products) and the shock wave in water surrounding the explosive charge. By making a least‐squares fit to the shock‐front data, it is possible to determine the peak shock‐front pressure as a function of distance from the cylinder wall. This has been done for 10‐cm and 20‐cm‐diam ANFO (ammonium nitrate/fuel oil) and aluminized ANFO (7.5 wt% Al) aquarium test data.
