Following the investigations of Richardson et al. (2005) and Korycansky and Asphaug (2006, 2008), we study the shape and spin state of rubble-pile asteroids and cometary nuclei, focusing here on the process and aftermath of tidal disruption. A fast and robust commercial physics engine (www.nvidia.com/physx) is used to model thousands of polyhedral elements including self-gravity and intergranular forces such as friction and cohesion. The physics engine has been tested and validated with small scale laboratory experiments (granular avalanche, brazil-nut effects); its speed and its ability to deal with resting contacts allow us to use a variety of element shapes, from simple primitives to arbitrary polyhedra. Here we model the tidal disruption of comet Shoemaker-Levy 9 and other split comets, extending the work of Asphaug and Benz (1996) to include bodies with realistic rubble properties. One result is that a modest cohesion can account for the absence of small tidal-disruption crater chains on Ganymede and Callisto.
