Simulations of low-speed impacts into cohesive aggregates and comparison with experiments on sintered glass bead agglomerates
Abstract
Small bodies of our Solar System show a great diversity in shapes, sizes and morphologies. However, we do not have direct information on their internal structure. The response of small bodies to various kinds of processes, such as impacts, depends on their internal properties in a way that is not yet well understood. It is therefore important to model the different kinds of structures that can represent a small body and to study their influence on the way a body responds to the different processes undergone during its lifetime. We recently adapted the parallel N-body code pkdgrav to the modeling of small bodies that are not fully monolithic but that have at least some degree of cohesion. Agglomerates of soft spheres bound together by spring forces that mimic their cohesion are used to represent these bodies. Here, we present a validation test of this adaptation, which consists of comparing low-speed impact experiments on glass bead agglomerates with simulations using the same impact conditions. <P />...
