PENETRATION AND CRATERING.
Abstract
The goals of this work are to discover what is happening in high-velocity impact, to attempt to understand these phenomena in terms of fundamental material properties and the fundamental laws of the mechanics of deformable bodies, and to use this information to formulate general theory which will adequately describe the physical processes occurring and which can be extrapolated to new situations with confidence. The plan to achieve these goals is to construct simplified mathematical and graphical models of the transient cratering process and then to test predictions made on the basis of the chosen model with the results of experiments. The experiments will determine the validity of the model under particular circumstances and will point the way to possible improvements in the model. The most fundamental questions of how the energy is divided among various competing processes and what the actual flow is have never been investigated. To correct this situation and provide basic information on the physical processes occurring in cratering, three general projects were instituted. They are: (1) an investigation of the energy distribution in cratering, (2) an investigation of flow and wave motion in cratering, and (3) an investigation of wave propagation in a rod.
