A Preliminary Model for Loads on a Penetrator Impacting Concrete

摘要

The research described in this report was designed to determine analytic equations providing loads on a penetrator element when the penetrator impact semi-infinite concrete at velocities to 500 m/s. It is assumed that the penetrator's trajectory is controlled with the application of all relevant forces to each penetrator element in a terradynamics computer code. The loading equations developed in this effort strictly apply only to two-dimensional plane or axisymmetric impacts since they were developed from hydrocode calculations of such situations. Drag coefficients and simplified trajectory equations are developed from the loading equations. (Author)
