Buffer capacity of granular matter to impact of spherical projectile based on discrete element method

Ying YAN, Pengfei LI, Shunying JI

Frontiers of Structural and Civil Engineering 2013, Volume 7, Issue 1,   Pages 50-54 doi: 10.1007/s11709-013-0186-x

Abstract: Granular matter possesses impact-absorbing property due to its energy dissipation character.adopted to simulate the impact of a spherical projectile on to a granular bed.The penetration depth of the projectile and the first impact peak are investigated with different bedthicknesses and impact velocities.The first impact peak is independent of bed thickness when the thickness is larger than the critical
