An Abrasion Algorithm for Ogive-Nose Steel Projectile Penetrating Concrete Target

A finite difference program is developed to predict the mass loss, nose shape change, and penetration depth of a steel projectile which penetrates into concrete targets based on the modified empirical equation of nose surface abrasion velocity and the assumption that the density of the projectile is constant. The model predictions are compared with the experimental results available in the literature, and good agreements are found between the present calculations and the experimental observations in terms of nose shape and mass loss.
