Numerical, Experimental and Analytical Investigation of Penetration ‎Depth of a rigid blunt projectile on the steel targets

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.‎
