Back on the subject of the failure itself, it is clearly understatement to suggest that a lot of extremely complex thought has gone into the scenario over the years - it seems there are a number of papers on the subject of computer models for fan containment and of non-axisymmetric loads generated when something goes wrong (typically an FBO), but I am not sure any address the possibility of the loss of the fan rotor and fancase in their entirety as I suppose that actually counts as ... ehm ... uncontained in one major sense!
For those interested, a start point might be the bright-coloured pictures - especially Figs 2, 5, 6, 7, 8, 9 in this (matching?) pair of papers. They share the same title but the second was published later so may be a revised version of the first - apologies, but I haven't managed to fully compare them:
