Abstract

The dynamic response of two-dimensional particulate aggregation with a dissimilar material layer subjected to the impact of a spherical projectile is investigated experimentally and also numerically using discrete element method. One layer of the two-dimensional particulate aggregation composed of nylon-66 spheres of 1/4 inch-diameter is replaced with alumina ceramics (Al2O3) spheres of same diameter. It is found from the distribution of normal contact force between spheres that the reflection of normal contact forces from the dissimilar material layer affects the scattering behavior of the particulate aggregation.
