Description |
A new theory to study the behavior of cylindrical explosives has been developed through the application of the equations governing mass, energy, and momentum conservation, an equation state, the Chapman-Jouget condition, and Newtonian mechanics. The resultant equation, D=DAinfe^(-a2/d), where D = the detonation velocity, Dinf= the detonation velocity at infinite diameter, a2 = the effective reaction zone length, and d = the diameter of the cylindrical charge, predicts a linear relationship between the logarithm of the detonation velocity and the reciprocal of the charge diameter. The validity of this equation is supported by graphs of experimental data. For a given set of data, two straight lines are often seen, indicating a mechanism change at some value of the diameter. This theory provides a new tool for further investigation of such mechanistic problems as well as failure conditions and other detonation phenomena. |
