Abstract
We developed an abrasion model that predicts mass loss and change in nose shape for steel projectiles that penetrate concrete targets. Mass loss data from four sets of experiments with two ogive-nose projectile geometries and concrete targets with limestone and quartz aggregates were used to develop the abrasion model. We plotted post-test mass loss versus initial kinetic energy and found a nearly linear dependence for striking velocities to approximately 1000 m/s. With this linear relationship, we derived a mathematical model that was implemented into the Sandia-developed, Eulerian hydrocode CTH. Predictions from CTH agreed well with experimental observations.
