The Experimental and Numerical Studies on the Penetrating into Concrete Targets with Kinetic Energy Projectiles

摘要

The normal penetration experiments of concrete targets subjected to 57mm diameter,semi-armour-piercing projectiles impact were conducted.The striking velocity,depth of impact crater and maximum penetration depth of the projectile were measured.The processes of the projectiles penetrating into concrete targets were numerically simulated using the LS-DYNA software.The results of numerical simulation are in good agreement with that of the experiments.The influence of the centroid of projectile on the oblique penetration process was studied.The numerical simulation results provide some references for the design of advanced penetrating weapon and protective structures.
