  • Based on the Kong-Fang concrete material model proposed recently and the three-dimensional mesoscopic model, the penetration of a typical warhead into rock-rubble overlays was numerically simulated. The influence of interface modelling of rock-rubble overlays on the projectile overload (or acceleration), penetration depth and failure in concrete and rock was discussed by considering two well-known methods, i.e., the conode method and surface-to-surface contact method. Numerical results demonstrated that the interface between concrete and rock is overestimated when using the conode method, leading to a larger projectile acceleration and a smaller penetration depth. While the surface-to-surface contact method underestimates the interface effect, resulting in a smaller projectile acceleration and a larger penetration depth. Furthermore, the damage evolutions are different: it is continuous and develops along the interface of concrete and rock using the conode method, while it is only continuous in the area near the projectile and becomes discontinuous beyond this area. Finally, based on the numerical simulations, the practical suggestions for engineering design of rock-rubble overlays are given.
