Scientific paper
Empirical relations linking the mass of the largest fragment, the kinetic energy released divided by the target mass, and the work done during impact are presented. It is found that the relation between the mass of the largest fragment, the mass of the target, and the work done during impact is not affected by the impact velocity. This work is seen as a useful means of describing phenomena associated with the impact destruction of rocks. On the basis of the empirical relations discussed here, a fragmentation model of the parent bodies of Eos and Koronis families is presented.
