DOT/FAA/AR-99/11 "Large Engine Uncontained Debris Analysis" which I posted a link to earlier contains both post-incident analysis and modelling information, and takes into account both the mechanical and aerodynamic forces at play when there is a failure. Even a quick scan makes it clear that the dynamics are very complicated, for example there may be secondary fragments caused by debris being ejected out of the front of the engine, then re-ingested and flung out again. Damage is to be expected both ahead and behind of the point of failure, although from looking at the diagrams it appears that the majority of it will be behind the point of failure.
