Additional Information Showing That a Cylinder's Material and Geometry Affect Measuring an Explosive's Gurney Velocity

In 2001, the thickness and properties of aluminum, steel, and copper cylinders were shown to affect the Gurney Velocity and Gurney Energy measured for Comp B explosive. This new work confirms the effects described in 2001 using experimental data for four additional explosives in cylinders of these and two more materials. The experimental data show a clear dependence between geometry, materials, and explosives. A new formula provides a relationship between an explosive's detonation rate and its Gurney Velocity as a function of cylinder and explosive geometry and densities.
