Comparative Research on Depth Empirical Formula of Projectile Oblique Penetration into Concrete

摘要：

　　The empirical formulas about the projectile penetration into concrete have been used widely,the calculation of oblique penetration is less,this paper describes several formulas about oblique penetration depth.The projectile velocity,penetration depth and angle of directional change are obtained from the tests of oblique penetration into concrete by 152mm artillery.The angular directional change is caused by the action of asymmetric resistance.The formulas of the projectile oblique penetration into concrete targets depth were calculated and compared,and the differences of the formulas calculated values and measured values were analyzed.It reached the conclusion that with the increase of the initial inclination angle,the effective penetration depth reduces significantly,the ricochet phenomenon occurs to a certain extent.
