Ballistic Performance Prediction for SC Jets.
Abstract
The performance of a shaped charge warhead is usually predicted based on an experimentally determined standoff curve valid for a specific target material. However, with the increased variety of target compositions the traditional “shoot and score†approach is not feasible anymore – neither financially nor with respect to time. In this paper, a combined analytical stochastic jet penetration model is presented that permits to predict the penetration process of a shaped charge jet into various target materials. The model combines (semi-) analytical descriptions of jet stretching and breakup with stochastic elements with an extended Walker-Anderson penetration model and an energy-based crater prediction to include the collision of particles with the crater wall.
