Bending of projectile with small angle of attack during high-speed penetration of concrete targets

The bending of the projectile in the process of high-speed penetrating concrete is studied by simplifying the projectile as a free-free beam. The bending moment caused by the transverse load which is generated from small angle of attack and penetration resistance is analyzed through theoretical work. The analysis showed that the theoretical bending condition is dominated by initial status, structure and material of the projectile. The computed results proved that the bending of high-speed penetrating projectile is affected by the existence of small angle of attack. The penetration experiment also indicates that the bending position and the bending condition obtained from experiment results are well agreed with theoretical analysis.
