Experimental Research for Penetration of Simulated Projectile into Concrete Targets

For three projectiles which size are reduced in proportion, the impact velocities and penetration process were measured and photographed by using the technique of electric probe and framing camera. The maxima of penetration depth corresponding to each impact velocity have been obtained, and through analyzing these data, an experiential formula for predicting the maximal penetration depth is developed, results show the data calculated from the formula are in good agreement not only with that of our experiments, but also with that in the reference.
