Abstract

Abstract

To study the effect of the concrete's mesoscopic factors on the deflection of the rigid projectile's ballistic trajectory, we established a 3-D mesoscopic model for the concrete based on the idea of randomly distributed aggregates, analyzed the causes and possible contributing factors of the ballistic trajectory deflection of the rigid projectile penetrating into a concrete target, and examined quantitatively the influence of the mesoscopic factors of the concrete. The results show that the mesoscopic concrete model is able to reflect the typical physical phenomena of a projectile's normal penetration, that the mesoscopic factors have significant effect on the deflection of the ballistic trajectory as the rigid projectile is penetrating into the mesoscopic concrete, and that there exists a characteristic ratio of the projectile's diameter to the largest possible diameter of the aggregate.
