Gurney equations - Wikipedia
The Gurney equations are a set of mathematical formulas used in explosives engineering to relate how fast an explosive will accelerate an adjacent layer of metal or other material when the explosive detonates. This determines how fast fragments are released by military explosives, how quickly shaped charge explosives accelerate their liners inwards, and in other calculations such as explosive welding where explosives force two metal sheets together and bond them. NettetThis equation may be integrated to give which has the form of the Mott-Gurney law, except that the current is reduced in the ratio 80. Equation (8) has been well established by experiments in many substances, 2.
