Abstract

In order to investigate the performances of corundum-rubble overlays subjected to small-diameter bomb penetration, a three-dimensional finite element model is developed. The model is used to study the projectile penetration into the corundum-rubble overlay by taking into account the randomness of corundum-rubble in size, shape and spatial distribution. This paper focuses on the following two aspects. The first is the effects of penetration conditions (such as projectile velocity, impact angle and position) on penetration depth and terminal yawing angle. The second is the influences of the constituted parameters for the corundum-rubble overlay (such as size and volume fraction of corundum-rubble, strength of grouted concrete). The numerical results are compared with the data from rock-rubble overlay, and better performances are found for the corundum-rubble overlay subjected to projectile penetration.
