Analysis of the Inclined Impact Resistance Characteristics of Concrete Structures Against Projectiles

Abstract

AbstractThe research involved the use of commonly utilized concrete materials as the target plate, with a specially designed 76 mm projectile intended to impact the concrete structure at a specific angle. The goal was to conduct numerical simulation research on the deflection of the projectile under oblique impact conditions and analyze the concrete structure’s ability to resist penetration under such conditions. Through numerical simulation calculations, various aspects of the oblique impact were studied, including ricochet patterns under different projectile velocities and angles of incidence, as well as the resulting damage to both the projectile and the target plate, penetration depth, and deflection angle of the projectile. The findings showed that, compared to vertical penetration, the concrete structure exhibited superior deflection and cover-plate effectiveness under oblique impact conditions. The ricochet patterns observed could potentially inform the design of concrete anti-ballistic structures.
