A new approach to modelling impacts on rubble pile asteroid simulants

The model presented in this work has two main applications: to better understand the stability of rubble pile asteroids against disruption, and to learn how the large-scale interior structure is imprinted to changes on the surface during non-disruptive cratering events away from the impact site. In this chapter the approach to modelling rubble pile simulants in impact simulations is described, and the sensitivity to the choice of initial parameters is tested.
