Numerically simulating impact disruptions of cohesive glass bead agglomerates using the soft-sphere discrete element method
Asteroids, Surfaces Collisional physics Geological processes Regoliths
2015/12/25
We present our implementation of cohesion in the parallel N-body code pkdgrav in order to model small bodies that are not fully monolithic but that have at least some degree of cohesion. Small bodies ...
