ANALYTICAL SOLUTION AND EXPERIMENTAL VERIFICATION OF SHAPED CHARGE JET PENETRATION

摘要

In the scope of this study a one dimensional shape charge code was developed using analytical and semi-empirical approaches. The penetration part of the code is based on the hydrodynamic theory of penetration. The code is capable of modeling and visualizing of shaped charge liner collapse, jet formation and target penetration. Factors affecting the penetration were investigated by utilizing the developed code. Since the code is based on the solution of some analytical expressions rather than the solution of finite difference equations, the solution cost comes out to be enormously less than those of 2 or 3 dimensional hydrocodes. Some number of experiments was performed by using copper liners on steel target plates. The results were compared with the developed code and a good consistency was obtained.
