To break a virtual engine in a computer simulation is cheaper than to break a real one. Consequently, simulations may be used to avoid some bad designs. Finally the number of "real tests" should be reduced thanks to the numerical simulation results.
such kind of simulation is extremely hard to perform, however, I do not see any reasons to do it... since all engines must be tested on the bird strike in reality
They showed a real life simulation of losing a blade in a Discovery show about the A380. The whole challenge was to keep the parts inside the engine from getting out because the engine basically exploded. And they said that it is something that happens once in a while.
@SlavaVB: When I and my high school physics class visited a turbine manufacturer (MTU, now part of Siemens) they showed us an actual blade that broke and then went through the housing of the power generator and then through the roof of the powerplant. That blade was found some 400 meters away from the generator, dug deep into a nearby crop field. These turbine blades have a lot of kinetic energy, for sure.

just because the failure of a fem model is less expensive than the failure of a real engine :)

What time interval is this and what rpm is rotating?

Oh snap, thats a lot of damage from one blade.
