The impact behavior of aggregated particles subjected to projectile impact at velocities less than 20 m/s is investigated experimentally. The aggregated particles consist of nylon spheres arranged randomly in a rectangular parallelepiped container. A steel sphere strikes obliquely several nylon spheres on the top of aggregated particles. The motion of aggregated particles and steel projectile is recorded by two high-speed video cameras. The effects of the impact velocity and impact angle of steel projectile on the motion of steel projectile and aggregated particles after impact are discussed in detail.
