Simply put, if a loss, injury or death is due to something bending or breaking, FEA can help explain the failure.

An experienced FEA expert can determine the stresses and displacements in the failed part. When compared to industry standards, earlier designs and competitive designs, this often identifies the cause of failure, and hence the responsible party.

As in any field, your choice of an expert is important in making your case. It's not unusual for an inexperienced FEA analyst to generate incorrect results; this is both a warning to the wise and a strategy for dealing with the other side's expert.

FEA results lend themselves to color plots and animations, making conveying the key concepts to the jury much easier.
