Analysis of Projectile Penetration into Concrete and Rock Targets

Abstract

This report presents several examples of penetration calculations for rigid projectiles impacting concrete and rock targets. The calculations were performed with a computer code which is based on the theory of dynamic cavity expansion in an elastic-plastic compressible continuum. The results of the penetration calculations compare favorably with available data from field experiments and with the results from published finite-difference code calculations. The influence of various target material parameters, different initial impact velocities, and projectile size and shape changes on concrete and rock penetration was also assessed. The accuracy and range of application of the penetration model, however, must still be determined experimentally under more diverse impact conditions.
