Abstract :
In this paper, the experimental, numerical, and analytical investigation of a blunt rigid projectile to the steel targets is discussed, Therefore, in the first part, the experimental tests are carried out to find the depth of penetration and the projectiles are cylindrical in diameter 10 mm and 20 mm in length with AISI 52100 and steel plates with dimensions of 120 × 100×10 are selected from AISI 1045. In the second part, the numerical simulation of the impact model in the Abacus software is carried out and the accuracy of the numerical model is verified with 8% error rate of the numerical solution with the experimental results. In the third section, presents an analytical model derived from the Chen analytical model and obtain the depth of projectile penetration. Finally, a comparison between experimental, numerical and analytical results is performed, the results obtained in three solutions (experimental, Numerical and analytical) have acceptable agreement.
