Penetration of reinforced concrete with ogive-nose penetrators

Abstract

We developed a model to estimate forces on ogive-nose penetrators launched into reinforced-concrete targets. Post-test target observations and triaxial tests on samples cored from concrete slabs guided the model development. The cylindrical, cavity-expansion approximation simplified the analysis to one-dimensional, radial motion, and an iterative procedure provided the solution technique for the partial differential equations. Graphical results show forces on nose shapes for a practical range of penetration velocities. © 1988.
