Abstract
Previous methods of relating explosive crater dimensions to explosive size involved the assumption that the cratering process was scalable. There are a number of shortcomings to these previous efforts, and the material presented in this paper avoids some of the difficulties of the scaling approach. A crude model of the cratering process is proposed from which a cratering formula is derived. The key feature of the model is that the hydrodynamic effects are separated from the ballistic effects. The free parameters of the formula are determined from experimental observations. The resulting formula is quite simple and should be applicable to engineering problems.
